Mail Bag: Turnarounds along I-10 East, resurfacing on Lp 1604 and more

I recently discovered a historical marker on Ammann Rd just east of SH 46, celebrating the Pinta Trail. If I had not checked out the Historical Commission of Texas' website, I would have never knew it existed. Are there not a lot of historical marker directional signage on state-maintained roads in Kendall County? I seem to see them in many other portions of the State, but maybe I'm missing the forest for the trees in my own area.
- Mark

This question caused us to go back to our Manual for Uniform Traffic Control Devices and our traffic operations gurus to find a good answer. Section 2M.11 covers these specific signs.
You're welcome to peruse the MUTCD on your own at any time. It's a handy guide for understanding the why's behind the what's with our signs.
Alright ... the answer (in plain English): We provide signs for all historical markers that are within our right-of-way and are outside city limits. In this case, the marker may have fallen outside our right-of-way and may even be in city limits.
If there are any markers you're seeing without these call-out signs that fit the bill of being in our right-of-way and are outside city limits, let us know!

The schematic for the IH 10 E & FM 1516 intersection calls for a complete reconfiguration, with turnarounds in both directions (for 1516) and two lanes in each direction for the underpass, including replacing existing riprap with retaining wall. Presently TSC has used the eastern half of the 1516 overpass to install an east-to-west turnaround. Why does this differ from the project schematic? And when will the 1516 intersection be reconfigured to match the schematic? If TSC bid an alternate to the schematic, why wasn't the public notified?
- Marshall

Great questions, Marshall. For argument's sake, let's use the schematics posted online as our base for this conversation. Fair?
These schematics are preliminary and used to explain what our overall vision for the project is. This vision remains.
Yes, we fully intend to construct turnarounds at the FM 1516 intersection as we had presented during our public meetings on the work being done. During the detailed design stages of the project we discovered an elevation issue with this intersection, however. If we were to construct the turnarounds under the current bridge, as shown in the preliminary schematics, we would end up with either (1) turnarounds rendered unusable by large trucks because the clearance under the bridge is too short or (2) major flooding problems from turnarounds cut deeply into the ground and set well below the elevation of the roadway around it.
The solution? Build a new bridge.
That's happening during the expansion of I-10 set to begin later next year. We're adding a lane in each direction between I-410 and Loop 1604. In doing this, we're also replacing many of the overpass bridges - including the bridge over FM 1516 - and making them longer, taller and wider. After this bridge work is done the turnarounds will be built permanently.
The turnarounds you're seeing built right now to serve eastbound-to-westbound traffic is a temporary turnaround conceived to ease traffic pressures at the intersection with the one-way roads. We've actually change-ordered this temporary turnaround into the contract Texas Sterling has; their plans never included the turnarounds earlier.

Why is the Thousand Oaks exit off I-35 closed and is this permanent?
- Lucille

It is permanent - and rather than call it "closed" we would call it "moved". We discussed this in a video post earlier, but we moved the exit south a bit to improve the overall operation of the highway out there.

I noticed Asphalt Milling Machines and rollers parked on this of 1604 West bound close to La Cantera. If this for a TxDOT project on 1604 or something else?
- Zane

Nope, that's us! We are resurfacing Loop 1604 (main lanes and frontage roads) between Bandera Road and Rogers Ranch/Bitters Road. Work started back in October and will continue until summer 2018. Expect to see daytime work on the frontage roads. We'll stay off the main lanes during the day, though. Don't expect to see that overnight activity until temperatures heat up, this upcoming spring.

On the SH 16 & 1604 project I see that the base is layers of asphalt. What's the life span for this method? It doesn't seem to work long on normal street traffic.
- Pamela

This is actually pretty standard for us. There are several layers to a roadway. The Express-News did a really interesting story about the Recipe for a Roadway almost two years ago. It's definitely worth a look.
Any roadway is a lot like an onion - there are several layers most of us never see or fully understand. What's more, those layers are not all asphalt - we often mistake other layers as mere digging or blading, when we're really building those additional non-asphalt layers.
Our depths are different than what you see on a city street or in your subdivision - that's important to keep in mind. While many municipal roadways measure their depth in inches, ours are measured in feet. That base of asphalt is at least 18 inches deep and rests atop base layers of a variety of compacted soils.

What is the status of putting the steel beams in place for hwy 151 over 410? I remember a while back it was supposed to occur in November. Now there appears to be no word of it. In fact it seems the hwy 90 work is going faster than 151.
- Steve

The beams should be here in January, and we could be setting beams as soon as February. This falls within the timeframe given back in June.
As for project pace, please do not refer to a single aspect of the projects to make an overall assessment of the progress of projects. Doing so can set yourself up for an unreasonable expectation on both projects.
To be honest, both jobs are on their predetermined pace; the 151-410 project is set to wrap up late summer 2018 as promised when we broke ground. The 410-90 project still has quite a bit of work remaining. While you're seeing steel beams placed, you'll carefully note the frontage work now nearly done on the 151-410 project has a long way to go. You'll also note the bridge work and work on the ramps at Marbach has just begun and has more than a year before that's complete. That sort of work on the 410-151 job has nearly finished.
Hopefully that helps.

(Re)Opening tomorrow: Northbound I-410 exit to Culebra

Crews with Williams Brothers Construction will have the northbound I-410 exit to Culebra Road reopened in time for the morning commute tomorrow - Wednesday, November 22.
We know that's more than seven months after we had initially promised to have the ramp reopened. We've discussed that issue previously, and the only thing we can really add to those explanations is a heartfelt expression of our regret we weren't able to keep the initial commitment.
The new ramp runs under the future northbound entrance from Military Drive, which is currently scheduled to open in the first quarter of 2018.
For those curious about other aspects of the project at I-410 and Hwy 151, here are a few quick hits:
  • The turnarounds at Ingram Road (and elsewhere) should be opened by the first part of 2018. We have asphalt work there that's very temperature-dependent and we are working out ways to get that done during the daytime without disrupting too badly traffic on the frontage roads.
  • The entirety of work on the main lanes of Hwy 151 is nearing completion, and we could have barriers removed and everything opened up fully as soon as Christmas. This includes, by the way, having that westbound ramp to Hunt Lane reopened. There are still some major items remaining, like concrete and asphalt work, but project bosses are telling us we should be able to squeeze all this in before Santa makes his rounds.
  • The steel beams to be set for the direct connectors are still planned to be set by February if all goes well. We have some closure restrictions for the San Antonio Stock Show and Rodeo coming up in February, so we can't commit to anything specific just yet. Please know we are as anxious as anyone to have those things in place and hope to do so around that timeframe.
  • The widening on the southbound frontage road of I-410 over Leon Creek should wrap up by January 2018, allowing us to get that frontage road back to full capacity and, perhaps, get that greenway under the road reopened for use.

Closures impeding Thanksgiving weekend travel?

If you're headed over the river and through the woods to Grandmother's house this week the last thing you're going to want to encounter is highway construction.
We feel the same way. The following note was sent to construction supervisors across our district a week ago. This covers all projects in Atascosa, Bandera, Bexar, Comal, Frio, Guadalupe, Kendall, Kerr, Medina, McMullen, Wilson and Uvalde counties.
The overall gist of the memo is simple: we should have no planned lane closures on major roads during the Thanksgiving holiday travel period, defined as beginning noon Wednesday and ending 10 pm Sunday. This doesn't mean we won't have any work going on, but it does mean that work will be done without needing closures.
During the holiday week both maintenance and construction inspectors will drive through projects to ensure major issues that crop up are dealt with in a timely manner. Things they'll specifically look for are work zone signs, barricade placement and pavement markings.
Before the holiday break comes crews will dress up the project areas as much as is practical.
One thing drivers can expect to see is a continuation of detours for long-term closures, like ramps or other features that have been closed long-term.
If something weird happens through the week our folks in the field will pass word along so we are able to post on our Twitter feed and get that information out there. We know many folks aren't on Twitter, but all major news outlets are and they follow us. If something weird happens, the news outlets will know and will be passing word along to you.
This isn't the only period on our calendar with such closure moratoriums. We'll have a similar prohibition on closures running December 15-January 2. Some minor exceptions may be made, but those are extremely rare.
These closure restrictions are long-running norms for us in the San Antonio District, by the way, and are designed to keep us out of your way during peak seasonal traffic and to allows everyone to stay just a little more safe as we prepare for that extra time with family.
And for those of you traveling beyond our little slice of Texas, check www.drivetexas.org for major closures across the great state of Texas. Please make sure you do not check the DriveTexas maps while driving; that's a job for someone in a passenger seat.

Mail Bag: new signal in New Braunfels, turnarounds at Marbach, 410-151 intersection

First, I want to say I am happy to see a traffic light at the intersection of Hwy 46 and FM 758 in New Braunfels! I travel through this intersection twice a day and it is very dangerous attempting to turn left onto 46 from FM 758. I would like to ask if we will see a flashing yellow left turn for 758 bound traffic from 46.
An instructive gif we used when we turned away
from the left turn yield on green arrangment in San Antonio.
I can already see a red left turn light there causing unnecessary congestion/delay and even making access to Clear Springs restaurant an issue for opposite 46 traffic.
- John

To paraphrase our traffic operations engineer: Yessir! This signal cycle will include a flashing yellow arrow signal. For those who don't know what that means, the flashing yellow arrow allows drivers taking a left to proceed cautiously if the coast is clear. This allows a better traffic flow and minimizes the need for long green time for a secondary movement at a signal.
Timing of the signal, once it's been installed and good to go, will be managed by our friends with the city of New Braunfels.

Closure of the turnarounds at Marbach was very bad planning. It is creating very bad traffic jams on the access roads. I can't believe this bad situation is going to last more than a year.
- Ed

We understand it's difficult, but it's necessary. With the amount of overhead work we're doing and the fact we need to work on the bridge support shelves (called abutments) it's simply impossible to keep the turnarounds open at a location like this. The closure is pretty standard for any construction of the type we're doing.
To mitigate the impact we are working with San Antonio Transportation and Capital Improvements, the city department with oversight for traffic signals and other roadway issues, to optimize the signal timing at the intersection to handle the additional traffic.
As for the duration ... well, we could have them opened back up a LOT faster if we were able to build the bridge all in one shot. That would mean, of course, fully closing I-410 for about eight months while we totally rebuilt the bridge. We'd carry all the main lanes traffic on the frontage roads through the Marbach intersection.

The last major rain event saw pretty bad puddling on the southbound I-410 exit for Hwy 151. What are you doing to fix this?
- Several

We added new asphalt to reverse the flow of water, and so far it's been working wonderfully. The water now runs to the area between the frontage road and exit ramp and drains to the north on up to Leon Creek. Barring a major rain storm, which brings puddling everywhere no matter what we do, we shouldn't see any major issues at this location as long as this temporary ramp is still in use.
Long-term, the exit ramp for Military Drive and the Westover Marketplace shopping center will move back to the north of Leon Creek. That's still on its way.

Closurepocalypse over; get ready for Closuregeddon

Last weekend we had major closures on US 90 at I-410 and on I-10 at Fair Oaks Parkway. Both went relatively smoothly (though that stretch of I-10 had a hiccup after our work was done with a big rig overturning Sunday).
If you avoided these areas per our recommendations, GREAT JOB!
Well ... we're doing it again and you probably want some information on what to expect for this weekend. We're calling it Closuregeddon, after last week's Closurepocalypse.
Here you go:
One closure we don't mention in the video you should probably take note of: I-35 between Walzem Road and Thousand Oaks. We'll have all lanes, both directions, closed Saturday (November 18) between 7 a.m. and 10 p.m. This will allow crews to work on overhead highway signs. This is a closure you'll want to avoid as well.


Closure moratoriums coming
We're just putting this out there - please spread the word.
We will have NO planned construction-related closures between noon November 22 and 10 p.m. November 26. You'll also see NO planned construction-related closures between 6 a.m. December 15 and 10 p.m. January 2.

Dust and vibrations along the US 281 project

Excess dust and feeling vibrations from excavation are common occurrences near construction, but can certainly be tiresome for those directly affected. We have heard your concerns about these issues along the US 281 corridor, and we want you to know that we’re working to mitigate its effects on you.
Today we'll discuss the issues directly - including their causes - and our solutions to lessen the impact on you.

Why all the dust and vibration?
Excess dust occurs during the excavation of rock when equipment creates fine particles that could easily become airborne with wind. Simple enough, yeah?
Vibrations felt from construction are caused by heavy equipment (and even traffic) using the roadway. The majority of the US 281 roadway sits on rock bedding. Any movements or loads on the that rock bed are easily transferred creating vibrations. The closer your home is to the construction site, the more likely it is that you may feel vibrations. This gets amplified when crews start digging and milling layers of rock to develop the road bed.

How are we minimizing the impact?
Preventing the creation of excess dust - dust abatement - is a priority on all our projects. There are several ways we can do this, and we are not limiting ourselves to just one. For instance, running extra water trucks along the site to moisturize the soil keep it from kicking up with wind has been somewhat effective. We use non-potable water wherever possible for this. Our construction crews and project team will also monitor wind speeds and directions prior to and during work to avoid sending dust downwind.
As for vibration ... well, we've already had Webber move some of its work to crush rock pulled from the ground away from sensitive work area. You should know we will not use any blasting techniques to break rock along the US 281 corridor as part of this project. Unfortunately, some of the vibration that will come when we use compactors to harden the layers of the roadway are going to be unavoidable.

When will these problems go away?
Once the US 281 frontage roads are complete – late 2018 - most concerns related to excess dust and vibration along the corridor should subside. At that point traffic will move outward, onto the new frontage road lanes, and construction activity will move to the main lanes area minimizing the chance of feeling vibrations. While the next phase of work on the project will still include activities causing vibration, those impacts will be way less than what you're feeling now. Since that stage of work involves significantly less excavation we also minimize the potential for construction-related dust.

Your takeaway

First of all ... we get it! We're hearing about the concerns and we want you to know these issues are a routine conversation on this project. Webber and our project management team continually work to mitigate construction-related impacts on those who live, work and play in the area.
If you have any additional questions, please do not hesitate to reach out.

Clearing the way for I-10 HOV lanes

We are only about eight weeks into work and the footprint of the future HOV lanes is already taking shape behind the concrete barriers.
The dirt work happening now to the inside of both the eastbound and westbound lanes really shows how the HOV lanes will fit into the I-10 corridor. If everything goes as planned these lanes will become available for use in a little more than a year, providing immediate relief for drivers along this increasingly congested corridor.
Not all our work is limited to the inside area of the HOV lanes, though. On the northern end of the project, near Ralph Fair Road, Flatiron Construction is building the foundation to extend the box culverts that will support the additional highway lanes. When we're all done that culvert will be eight boxes wide!
Work on the outside lines not near Ralph Fair Road is intended to develop a temporary bit of asphalt so we can shift traffic over and give crews more room to build those HOV lanes. This is pretty common for expansion projects like this.
Through Thanksgiving work will continue on the culvert extension and on bridge support columns. Expect lane closures nightly, Sunday nights through Thursday nights, with no closures on Fridays or Saturdays. During the week of Thanksgiving crews will skip Wednesday night and Thursday night but return to action Friday night, November 24th.
Be sure to check back after Thanksgiving for another look-ahead on what to expect during your daily or nightly commute.

Steel beams to be set over I-410 ... at US 90

Williams Brothers Construction will place steel bridge beams over I-410 at US Hwy 90 over the next two weekends, requiring a near complete shut-down of the busy interchange each weekend.
The beams will form the future eastbound Loop 1604 ramp to northbound I-410.
There's no quick-and-easy explanation of these closures, so we'll be very deliberate covering each direction. Please pay attention to the specific direction you may be traveling (look for a video of this next week).

Nov. 10-13 closure
Beginning Friday, November 10 at 8 p.m. all lanes - frontage road and main lanes - of US Hwy 90 will close at I-410. The main lanes of I-410 will not be affected.
  • Eastbound traffic will take southbound I-410 to Valley Hi, turn around and return to US Hwy 90.
  • Westbound traffic will take northbound I-410 to Hwy 151, turn around and return to US Hwy 90.
  • Southbound I-410 traffic to westbound US 90 will not be affected.
  • Southbound I-410 traffic to eastbound US 90 will exit Valley Hi, turn around and return to US 90 via the northbound frontage road of I-410.
  • Northbound I-410 traffic to eastbound US 90 will not be affected.
  • Northbound I-410 traffic to westbound US 90 will exit Hwy 151, turn around and return to US 90 via the southbound main lanes and frontage roads.
  • All other directions will follow their normal paths.
All lanes will be reopened by 5 a.m. November 13.

Nov. 17-20 closure
Beginning Friday, November 17 at 8 p.m. all lanes - frontage road and main lanes - of I-410 will close at US Hwy 90. The main lanes of US 90 will not be affected.
  • Southbound traffic will exit westbound US Hwy 90 to Hunt Lane, turn around and return to I-410.
  • Northbound traffic will exit eastbound US Hwy 90 to Military Drive, turn around and return to I-410.
  • Eastbound US 90 traffic to northbound I-410 will exit Military Drive, turn around and return to I-410 via the frontage road.
  • Westbound US 90 traffic to southbound I-410 will exit Hunt lane, turn around and return to I-410 via the frontage road.
  • Southbound I-410 traffic to eastbound US 90 will exit US 90 west and turn around at Hunt Lane.
  • Northbound I-410 traffic to westbound US 90 will exit US 90 east and turn around at Military Drive.
All lanes will be reopened by 5 a.m. November 20.

Overnight work, too
The steel beams, once set, will need to be welded into place and have the temporary bracings removed. This will take about a month to accomplish with overnight closures employed to get the job done. These closures will be confined to the main lanes and be in one direction only, with the exception of two or three nights of work over the heart of US 90 and another two or three nights of work over the heart of I-410.
The nights with full closures in both directions will be announced via social media as they are scheduled.
As a rule of thumb, expect closures on US 90 every night between November 13-22 and November 27-30. Expect the same activity on I-410 between November 29 and December 22. If you noted the dates overlap a bit, let us put your mind at ease: we will NOT close both US 90 and I-410 at this location simultaneously.

Hwy 46 getting a new road surface next few weeks

If your commute in New Braunfels includes Hwy 46 between I-35 and FM 758 expect minor delays due to construction between November 6 and November 17.


What/When
Overnight closures of the middle portion of Hwy 46 between I-35 and FM 758 tomorrow (Thursday) night, Friday night, Saturday night and Sunday night. Each night crews will begin about 8 p.m. and will be cleared out by 6 a.m. each morning.
Daytime closures of alternating lanes on Hwy 46 between I-35 and FM 758 begin Monday, November 6 and will run through Friday, November 17. Work will begin 9 a.m. and wrap up by 4 p.m. each day.
During the daytime closures we will make sure we have one lane open in each direction. The last few days of this closure will be a "rolling" closure, with crews slowly progressing along the route.


Why/How
We are resurfacing Hwy 46, and we're almost done with the work we've been tackling out there the last few months. The overnight work will let us mill the middle of the road to just about match what's out there on the rest of the road right now.
The daytime work will allow asphalt crews to do their thing. The top layer of asphalt we're laying is a fairly thin layer of specialized surface asphalt. Because of the way it's made up and because of how thin it is, we have to have temperatures of 70 degrees and rising. This pretty much prevents us from doing work overnight this time of the year.
Once pavers are done with their work a striping crew will follow to set lane markers.


By the way
A new traffic signal on Hwy 46 at FM 758 will be installed November 6. It should only take a day to install, so if you drive through the area expect to see those flashing beacons replaced by a full signal during your evening commute.
If something pops up to delay us at all, that signal will be in action by November 7.
Ordinarily we put new signals on "flash" mode to drum up awareness of the signal. In this case, since a beacon already exists at this spot, we're going to go ahead and immediately turn the signal on with full functionality.

I-35 SAMMC project: is the new ramp to Randolph/Starlight forever

We're sorry we weren't able to get anything out about this before the weekend; the switch kind of popped up on our communications team last week and we weren't able to get this done before now. We're sorry!
Here's a brief look at the new configuration of I-35 in the Windcrest area:

Monday, October 30

Mail Bag: West Military at Lp 1604, I-10 developments, FM 1103 and the New Braunfels Ave Bridge

I live in Rogers Ranch, and we see construction signs posted on Rogers Ranch Parkway for work on the intersection with 1604. Can you tell us what will be done there? We hope it will add turnaround lanes.
- Michael

Michael, we had several of your neighbors reach out on this. Perhaps you've already gotten word ... but if not, please spread the word now.
We've got a simple overlay project going on between Rogers Ranch Pkwy and Bandera Road. That means we'll be shaving off the top 2 inches or so of asphalt and replacing it with a fresh layer of asphalt. Work on the main lanes is overnight only - that stuff won't happen until we get back to warmer temperatures. During the daytime we're allowing the contractor to move forward with the frontage roads.
All told, you'll see us doing this work for the next nine months.
No turnaround lanes are coming ... yet. We do have a future project adding turnarounds, but we're about two years from seeking bids on that one. Sorry it's not sooner.

Just a quick observation on the I-10 east at 1516 frontage road conversion to one-way. Converting the frontage roads to one-way before the 1516 intersection improvements was a horrible idea and potentially more unsafe than two-way. There is lots and lots of traffic from the landfill and other businesses along the southern frontage road between Foster and FM 1516 that now has to travel east to the four-way stop at 1516. This has the frontage road extremely backed up. The exit ramp to 1516 is also backed up onto the highway causing an extremely unsafe condition of waiting to exit on the shoulder with traffic passing inches away at 70-plus miles per hour. It might be a good idea to get started on the 1516 intersection improvements soon!
- Marshall

Turnarounds at FM 1516 and Loop 1604 are not happening until a future project; those are not included in this project. That goes for the traffic signals at FM 1516 as well.
You'll see some improvement when the intersection at Woodlake Parkway is finished in 2018, and Texas Sterling Construction is working to build up the inside halves of the frontage roads so they can also build the new exit and entrance ramps. Both of these will help quite a bit.
Ultimately the decision to fast-track the conversion of frontage roads was made by our area engineer, who felt strongly this would improve safety by eliminating early the two-way frontage roads.

Why does TXDOT San Antonio keep listing Schertz as Selma in your weekly construction-related closures? Confusing.
- Concerned Citizen
We'd like to blame a map that's not incredibly clear on boundaries:
We drove through I-35 over the weekend to verify city limits and checked with our stakeholder lists, and found Selma isn't really involved here. We apologize for the error and any confusion it's brought - we should have verified this long ago. We have adjusted the most recent closures post to reflect the correction.

There have been a lot of crashes along I-10 between Boerne and 1604 since the recent construction projects. Is the traffic behaving as modeled? Should we anticipate further construction progress due to the continued development in the area?
- Rob
Any time a crash happens you can probably bet traffic isn't behaving as modeled.
We're not seeing a statistical spike in crashes along the I-10 corridor right now, but these crashes are typically more dramatic when a project is active.
As for continued development ... yes! We have a few major jobs still on their way over the next five years:
  • Conversion of frontage roads to one-way between Fair Oaks Parkway and Balcones Creek
  • Construction of a new overpass at Balcones Creek Parkway
  • Conversion of frontage roads to one-way between Balcones Creek and Scenic Loop Road
  • Conversion of frontage roads to one-way between Scenic Look Road and Hwy 46
Just to give you an idea.


What is going on with Military Drive West? We're currently on "traffic switch" number 2 but there is a new sign advising of a traffic switch on 18-18-17 - I assume that's supposed to be 10-18-17? Does this mean the traffic direction is going back to normal for now or are we going to be going sideways while driving backwards?
- Kim
Apologies for the typo in the digital message board. Those happen from time to time and we do our best to catch the issues quickly.
Where we know and have published several stages of traffic shifts, a generic "traffic switch" message on a board should alert folks to the next phase happening.
More to the point at this location: we will have the left turn lanes opened up in about a month (by time we reached the 18th we had traffic all where it started, except those turn lanes) with fresh striping to keep everyone in their lane. That will only last about 6-8 months, though, as we'll be ready to move traffic over onto the frontage road at that spot summer 2018.

I don't have a question....just a comment! I think you should KEEP the New Braunfels Avenue Bridge the way it is with the wonky arches.....it's one of a kind and a funny story!!!!
- Marci
We're glad you appreciated the story out there and are able to find some humor in it. We're still not going to keep the wonky arches. As we explained in our post the arches will be re-done once the remainder of the bridge is built and we can move traffic away from the edge there.

On the La Cantera Pkwy to Ralph Fair Rd project, I thought the work is only done on the inside lanes. Why are barriers being set on the outside as well? Also what is being done to the drain structure when going westbound right before Ralph Fair Rd light on Leon Creek? I thought that was done during the previous project?
- Danko

Let's start with the building one side and the other thing.
We're building on both sides of the road - first to the inside, then to the outside. In order to make room to fully build the new HOV lanes on the inside of the current main lanes, we're adding some "temporary" pavement to the outside. This will allow us to shift traffic over just a few feet so we can really get going on that inside lane.
As for the drain structure work that seems to be redone, we're not really re-doing any work done by Texas Sterling Construction in the previous project. Here we've got box culverts running under the main lanes of I-10 that need to be extended for the additional width of the highway.

The New Braunfels Ave bridge debacle

About a year ago we started the process of replacing the old New Braunfels Avenue overpass - the old one was damaged and prone to getting hit by semi trucks. These bridge replacements are typically done in halves so we continue to carry traffic on the bridge while it's being built.
A few weeks ago we finished the first new half of the bridge and demolished the remainder of the old bridge. The new bridge had everything - sidewalks and decorative arches included.
It looks ... well, terrible.
No two ways about it, the concrete barrier along the new portion of the overpass we're building over I-35 near the Government Hill neighborhood didn't turn out the way it was planned.
First of all, the structural integrity of the bridge is fine - the issue is purely aesthetic. It's still super embarrassing for everyone involved. With that preface, let's get through the brass tacks here.

What in the heck happened?
The arched windows of the bridge rail are made by pieces of Styrofoam inside the concrete forms. When concrete was poured these Styrofoam chunks shifted. In some cases they shifted a lot. Nobody could see what was happening until the forms were removed, which happened the weekend we demolished the remainder of the old bridge.

Who was supposed to be watching this thing?
We have a consultant group watching our construction activity on this project. SAM-Construction Services has a team overseeing the work done by CRG, our prime contractor. In order to avoid project lag they asked Bexar Metro Area Engineer Eddie Reyes if they could demolish the old bridge the same weekend they had the new portions structurally ready for traffic - something that had initially been planned to happen at least a week prior to the demo work.
Since the problem happened inside a concrete form, nobody could see the issue until the forms were wrecked. The foam cutouts couldn't be observed; there was no way to know things had floated so far out of whack.

Did TxDOT pay for it?
Project Engineer Jon Green says we only paid labor costs and for some materials; we haven't paid for the whole bridge rail. That payment will come when the rail is reconstructed correctly.

How are we fixing this?
By time this defect was discovered the old bridge had already been demolished and we needed to be able to put traffic on the new bridge, where folks are driving today. With the tight constraints of the bridge we simply don't have enough workspace to solve the problem yet.
The good news: once the remaining half of the bridge is constructed we can move traffic away from the defective rail and reconstruct it. That will be done at CRG's cost.
In the meantime the project team is re-thinking the way the forms are made to prevent this frustration from happening on the other bridge rail.

What is the bridge going to look like?
This is answered better with some pictures - you should be able to click to enlarge.
Here's the overall bridge overview:
And the detail of the arches:
No, the arches won't be pointy:

Loop 337 expansion in New Braunfels to start

A four-year, $43.3 million, project expanding Loop 337 to a four-lane divided highway between Hillcrest Drive and Altgelt Lane starts this week with Hunter Industries working immediately on setting barricades and on clearing work areas within right-of-way but off the existing road.
A formal groundbreaking by the city of New Braunfels will take place November 15 at 10 a.m. at the Oakwood Baptist Church.
Whew. That was a keyboardful. It gets you the nuts and bolts, though. Let's now turn to details.

Project overview
Loop 337 has long been a two-lane road looping around New Braunfels and connecting commercial hubs along the north end of the city, the growing west side and along the south end. We are expanding the road to a four-lane divided highway while adding sidewalks along the entire thing.
It's not an expressway, so current intersections will look pretty well the same - just with a whole lot more traffic capacity on Loop 337. This means existing bridges over Landa, Hwy 46 and Rock Street/Gruene Road will be expanded. Other intersections will remain signalized.

What to expect
First of all, this project will be going for about four years - expect work to continue through the end of 2021. Hunter Industries has a reputation in the New Braunfels community for moving projects along quickly and staying on schedule ... but that doesn't mean they'll be able to wrap up a four-year-job in two years. If you live, work or play along Loop 337 (which is pretty much all of New Braunfels) expect to see work every bit of those four years.
The good news is the work is almost entirely outside the active traffic lanes. Closures will be extremely minimal and limited to overnight hours between 8 p.m. and 6 a.m. We won't be working Friday or Saturday nights. Hunter Industries will typically be out there six days a week.
By contract we won't close two consecutive intersections at the same time.
We are already aware of big events in the area - like Wurstfest or the Comal County Fair - and will make sure we're not getting in the way.

The first few weeks
The first work on any project is setting barrier and clearing right-of-way. None of that will impact your daily traffic.
Hunter wants to begin the heavy lifting by working on bridges - that work will be, after all, the heaviest of the project. We have seven bridges being built on the job, and Hunter's folks say they'd like to begin on the bridges over Gruene Road and over the Guadalupe River.
None of this work will impact daily traffic.

If you're a Unicorn
Don't plan on using construction as an excuse for being late to class, first of all. We will not be doling out excuse slips for students any time soon.
During the first phase of work you'll see no change in the way traffic moves in front of New Braunfels High School. That first phase will last about two years.
Come time this year's freshmen are getting ready to drive we'll have southbound traffic all on the new lanes and kids coming out of the school will need to use turnarounds designed to make the corridor safer to reach the new lanes. We'll have details about the daily view of traffic during later phases when they come about.

Phasing
The first phase will construct - almost completely - the new southbound lanes. This includes all seven new bridges as well as new sidewalks. Crossovers along the route between the northbound and southbound lanes will be built at this stage as well. The first phase will take about two years.
During phases two and three we'll move southbound traffic onto its new path (but it'll still just be one lane) and keep the northbound side where it's at while we rebuild the northbound lanes in halves.  Each of these phases will take about a year.
The final phase, which will only take a few months, will be the final surface of asphalt.
