I-10 closures (yesterday)

First of all, we owe folks traveling along the northwest corridor of San Antonio a huge apology - we are sorry.
Yesterday (December 21) we had two small segments of westbound I-10 between Ralph Fair Road and Fair Oaks Parkway limited to a single lane and traffic was backed up significantly, causing reported delays of well over an hour. We'd like to explain ourselves a bit.


What we did
For the record, this is a
highway in Oklahoma
published by Equipment World
back in 2015; it is NOT
representative of our roads
in/around San Antonio.
The closures were for emergency repairs to the roadway. Recent wet weather opened a pothole near Ralph Fair Road and caused significant issues on I-10 Tuesday morning. Our guys got out there and created a temporary patch, but it was done during wet-weather conditions. We knew it wouldn't hold up through Christmas.
Yesterday was our opportunity to get in while the ground was dry and do something that would hold a bit better and we reduced significantly the odds of a safety hazard cropping up over Christmas and New Years.
We had another pothole open up near Fair Oaks Parkway we addressed with a long-term fix immediately.


Why we did it
Again, these repairs needed to be done immediately. Waiting wasn't an option; we tried that the first round with the pothole near Ralph Fair Road. That pothole was reported over the weekend and inspected Monday (December 18). We tried to hold off on repairing for a better time, and the pothole simply got worse and created bigger problems by Tuesday.
We simply had no choice but take care of the issue now and not try waiting until after the week of Christmas and New Year.


Why not at night
Asphalt work requires warmer temperatures, often above 60 degrees. We're not getting those warmer temperatures during the nighttime hours, so we had to get the work done during the day.
We know it stinks, and it's not a decision we take lightly at all. We actually have a moratorium on planned construction-related closures this week (and next), and we won't typically do a planned closure on the main lanes of a highway during a weekday anyway.
The point is this: it wasn't poor planning, but poor timing by Mother Nature.


Where we failed

Our communications staff failed to get notice out in a meaningful way. This is what we're apologizing for.
We have in the past been successful alerting folks to unfortunate closures like this. Our goal is simple: let folks know what's happening so they're not left wondering while they sit in traffic. When we got an email from a member of one of our own construction project teams working along I-10 asking why we had the backup we knew we dropped the ball pretty badly.
We should have posted alerts to Twitter and had a blog post explaining the closure. We know traditional media outlets - TV stations, newspaper and radio stations - pick up news bits from our Twitter feeds and our blog. We should have posted the closure to our Drive Texas online travel app. We should have coordinated messaging through our digital message boards operated by TransGuide.
We did none of these.
Travelers were left instead wondering the cause of the long delays near busy shopping centers and along major travel corridors.


What we've learned
The online assets we've used in the past are effective and should be used more consistently in the future - indeed, we will use more consistently in the future. Frankly, we know we can do better - we have done better in the past - and we will do so moving forward. Expect to see us post to Twitter with the hope it gets picked up by traditional media out lets. Expect to see something on our blog.
And if you're listening to satellite radio or your MP3 player, expect to see our digital message boards alerting drivers of the closure. Expect to see something like this on the Drive Texas app.

Wurzbach and Northwest Military - your chance to be heard

It could be your last chance to provide input on the future of the intersection of Wurzbach Parkway and Northwest Military.
The current plan, based on input from previous open houses hosted by our planning team, is to expand the intersection without building bridges. Challenges with access between the Inverness neighborhood and the Alon Business Center led to scrapping plans with an overpass in favor for an expanded signalized intersection. Traffic engineers estimate morning delays at the intersection improve from 47 seconds to 34 seconds with this solution; evening delay will improve from 77 seconds to 36 seconds, elevating the current level-of-service rating an entire grade.
The current proposal extends all right-turn lanes for added storage space and includes dual left-turn lanes in all directions. The estimated cost as of today is about $7.5 million.
This is all based on current public input. Those yet wishing to be heard may provide their input at our final planned open house tomorrow night. Here's the info:
  • Thursday, Dec. 15 between 5 and 7 p.m.
  • Barshop Jewish Community Center Auditorium, 12500 NW Military Hwy
The meeting will be an open house format so residents may come and go at their convenience and staff will be available to answer questions.
Construction on the project could start as early as 2020.

The latest on Austin Streeet in Seguin

UPDATE: upcoming work involving closures has been pushed until after New Years due to the wet weather forecast. New work schedule will be announced early January.


If you're talking with our guys on the project please don't mention the word inlet - it's become profanity of on this project. Whether the issue be with fabrication or installation, drain inlets have been a single consistent challenge on this project.
Because of some of these challenges on the south end of the project we are going to close - completely - North Austin between Seideman and Railroad. This will allow Curran to reconstruct the road and reposition some of the inlets in the area, correcting the issues causing problems for us right now.
Oh, yeah ... it would be helpful to know the timeframe of that full closure. Well, we plan to take advantage of the school holiday so we won't need to reroute Seguin ISD school buses. Curran will shut things down the morning of Monday, December 18 and will reopen the road by close of business Friday, December 22.
If we tried to do this work without the full closure we'd end up trying to finish it out with weekend closures through the month of January. This more aggressive approach allows us to save some time on the work and get down to business.
Back in October we said we'd be all done with one-way traffic on this job forever. We're still on pace to make good on that promise. Curran is laying asphalt on the northbound side of the road and has just a couple of inches remaining before we can swap lanes over and work on the southbound side.
All told we're eying a completion date in early 2019. Yes, that's about six months after we had initially expected. Delays involving those cursed inlets and some box culverts have pushed work back and contributed to some fairly significant delays on work.
And now ... time for some quick looks at the job:

Paving crews lay asphalt base for the new road. The elevation difference between the old road and new road should be fairly evident; the old road surface is about even with the workers' waistline as they lay asphalt.

This stretch of northbound Austin Street still needs a good two inches of asphalt before it's ready for traffic.

Box culverts and inlets continue to be a challenge on the project, but the challenge is being met by project staff head-on.


Inlet woes continue to plague the job, but TxDOT staff has worked with Curran to develop workable solutions and get this job finished with relative speed.

Mail Bag: Congested highways, stewardship and some future planning

Why is traffic on 1604 east bound between 281 and Bulverde Road moving so slowly in the afternoons? My trip home has increased by 40 minutes.
- Nan
Why has traffic increased so much recently? I-35 has turned into a parking lot!
- Ericka

Honestly, that's probably because of the area being among the fastest-growing in the United States. For some reason, people love coming here! We think it has something to do with the tacos....
It's why we have major construction along seemingly every corridor - to address the congestion and safety issues that come from adding dozens of cars to our roads each week.

Recent advance notices refer to nightly closures, but nothing about day time closures of the right lane of US 281 NBFR north of Loop 1604. The TCP on the TxDOT website shows permanent pavement added to the left side of the NBFR which avoids the lane closure. Have the plans changed?
- Tom

First of all, we don't have our traffic control plan (TCP) posted online.
When we add permanent pavement to one side of the road, we often need to shift traffic away from that area to create adequate safe work space. That sometimes means adding some temporary pavement to hold traffic for a few weeks or months as needed - which means closures on both sides of the road.
Frankly, any time we do any construction project, every lane will be subject to occasional small closures at some point of the work.

Is Evans Road from Green Mountain to Bulverde Road closed again today (12.5.17)?
- Gladys

First of all, we're sorry we didn't answer this question a bit sooner. The questions to the Mail Bag aren't checked daily, and the Mail Bag isn't intended for immediate reply. For faster responses try us on Twitter.
As for the Evans Road work, that's not TxDOT work anyway. That work was done by SAWS, and questions about the work should have been directed to them.

I noticed the work on I-10 at Old Fredricksuburg and at Scenic Loop is adding extended sections of concrete roadway. Will the widening of I-10 to The Rim also use concrete? Is there a reason the approaches to the bridges were concrete in these projects?
Also, at Old Fred, the retaining walls are prepared for widening the bridge. When is that planned?
- Blake

We are trying to move toward concrete paving wherever we can afford to do so due to the lower cost of long-term maintenance. Going with concrete is super expensive on the front end, though, and isn't something we're able to do with just any project. We typically extend the concrete paving at elevated bridges, such as the overpasses you're mentioning, to accomplish some of our goal.
The HOV lanes we're building between La Cantera and Fair Oaks are not being build on concrete except on the bridges we'll be expanding.
We're glad you noticed the forward-thinking design on the new overpass at Old Fredericksburg Road - we do not have a date for that expansion set, but we wanted to be sure the new bridge would improve constructability for the projects that may come in the future.

I appreciate what you do getting the word out to the SA community on their TxDOT projects. I live in northeast San Antonio and the I-35 project there impacts me greatly. I was wondering if the southbound I-35 exit to Walzem will be relocated. I know you have relocated the I-410 Walzem exit, even though I see people not using it and using the old exit instead.
My worry is if the exit is not closed, we will continue to see traffic occasionally back up onto the main lanes when there is a train. I know that there is one lane of SB I-35 access road that is continuous through the I-35/I-410 interchange. Is this section being only one lane prohibiting the relocation of this exit?
- Nathan

For now we are not relocating that southbound I-35 exit to Walzem. Your suggestion is really interesting, though - it's something we're passing along to our highway planners as an option we ought to consider for improved operational efficiency.

Seal coats - what they are and why we do them

We've received a slew of comments and complaints about seal coat projects across the region over the last several weeks. It's an annual occurrence for us, answering these questions. Each of them typically echo much of what John, who submitted this question late November, has said:

Recently TXDOT hired some contractors to lay down a layer of rocks on FM 758. The road is now worse than ever. I drive the road daily. Prior to this I never had rocks hitting my car. I have had 5 rocks hit my car in the last week alone from cars passing while waiting to turn onto the road or by cars passing in opposite lane. I now have 2 new chips in my windshield. I have never seen this surface on a highway before. Is it temporary and why not replace with a smooth surface like it was?
- John


The elements of the complaint are fairly easily broken down:
  • The road is in horrible shape and covered in loose gravel
  • Rocks are spraying cars damaging windshields and paint jobs
  • This is poor workmanship the likes of which has never been seen
The truth is most people don't understand what exactly has been done. That's fully on us, by the way - it's up to us to let folks know what's going on, and it's clear we missed that boat (though others have taken the issue up...). Late is better than never, though, correct?

What is a sealcoat?
Sealcoats are intended to moisturize the road to prevent crumbling and extend the life of the pavement.
Asphalt is an amorphous solid dependent on a level of wetness for its structural integrity. Just like our skin, it chaps and cracks in the hot Texas sun. While many add lotion to preserve soft and silky smooth skin, highway engineers add a cocktail of oil and tar to the road to preserve its shape and smoothness. Over time the cocktail seeps into the road, but when we first apply the mix it sets on the surface of the road.
Anyone who has seen a James Bond movie or played Spy Hunter knows how treacherous a road with oil concentrated on the surface can be. To keep a road we've done a seal coat on safe and to improve traction we lay a thin, sparse layer of gravel atop the seal coat mix.

Why not just resurface?
This is a common solution posed by most who drive these newly sealed roads. Heck, we'd love to be able to resurface or reconstruct each road every time we see wear and tear, but the cost would be astronomic. We reserve resurfacing for about every 7-10 years, and seal coat about every 3-5 years.
The cost difference is huge and cannot be overstated. A seal coat will cost literally pennies on the dollar we might spend resurfacing the road. While we are committed to providing and maintaining a safe and reliable transportation system, we are tasked and trusted to be extremely prudent with the limited taxpayer dollars we are given.
The bottom line: sure, resurfacing the road would look a lot nicer. This practice about doubles the lifespan of a road, though, and cuts costs by nearly 20 percent over a 40-year timeframe.

What about the slinging gravel?
The result is a road that looks really dark, like a new road, but has a bit of what looks like loose gravel on its surface. That gravel is mashed into the road surface, typically, using rubber-tired pneumatic rollers.
Although the result is a louder ride with road noise, the biggest problem for drivers comes from the gravel kicking up with the large knobby tires from the trucks on the road. This is why we typically keep "Loose Gravel" warning signs up while we're doing the work, letting drivers know to take care and increase following distances.
After a few short weeks that gravel gets pressed and ground into the road surface and becomes a non-issue.
