Major I-35 closure next weekend

If you haven't heard by now, we have major closures of I-10 at Fair Oaks Parkway planned this weekend and next weekend. We just got word from our field staff of another closure you'll want to know about.

When
Friday, August 25 at 9 p.m. until Monday, August 28 at 5 a.m.

Where
I-35 main lanes at New Braunfels Avenue on the east side of San Antonio. Also, the New Braunfels Avenue overpass at I-35.

What
We're closing the main lanes of I-35 while crews demolish the old New Braunfels Avenue overpass. Traffic will exit New Braunfels Avenue, move through the intersection and re-enter the highway at the first available ramp. Off-duty officers will help move traffic through the New Braunfels Avenue intersection.
We are also closing the New Braunfels Avenue overpass. Traffic on New Braunfels Avenue will have right-in, right-out only access during this weekend's closure. Those hoping to cross over I-35 should do so at Walters or Pine to do so.

Why
This closure enables crews to safely demolish the old bridge, which we are replacing with this project. Any time we do work like this overhead we close the road so we don't risk catastrophe with people underneath. In this case the bridge will be demolished and pieces of the bridge will be falling onto the road beneath.
Don't worry about that road, though. Before we start the demolition crews will spread a thick bed of sand or dirt on the road to cushion the fall of debris and ensure the road is protected. After the debris is cleared away that dirt bed will be scooped and swept up. Once the work is finished and the main lanes of the highway are deemed safe we will open things up.
And no, we won't use dynamite like crews did up in Marble Falls a couple of years ago. Our guys will be using excavators mounted with hydraulic jackhammers. Not super exciting or as fun to watch as the Marble Falls bridge demo was, but it gets the job done.

Worth noting
This is one of two bridge demolitions occurring in the San Antonio area during the weekend of August 25-28. As we pointed out to begin this post, the other will be on I-10 at Fair Oaks Parkway.

Next I-10 closures at Fair Oaks Pkwy

We have two more weekend-long closures impacting I-10 at Fair Oaks Parkway coming in August. And, to be completely honest, these are going to be doozies. They'll have a greater impact, by far, than the previous two closures.
Here's a look at what's going on, taking things chronologically:
August 18-21
This closure will have little impact on the main lanes of I-10 but will be significant for the intersections on the frontage roads. Actually, we will completely close the intersections - on both sides - at Fair Oaks Parkway.
Work will begin about 9 o'clock Friday night (August 18) and finish no later than Monday morning (August 21) at 5 o'clock. We are hoping to be wrapped up with this work a little early, though.
When work is done all traffic on the Fair Oaks Parkway bridge will be moved onto the turnaround bridge. Yes, there is enough space - just enough for a pair of narrow travel lanes. Nothing too extreme, but it was built wide enough to accommodate traffic for the detour.
During the closure we'll have some pretty interesting detours in place. Since a picture is worth a thousand words, here's what things will look like (click on it to enlarge):
The orange area is the work area - and will be completely closed through the weekend of August 18-21.
Those trying to reach Fair Oaks Parkway may do so through Leslie Pfeiffer Drive. Those trying to get to Tarpon Drive need to use Windwood Drive. If you're headed to those businesses in the area, you'll do so following the same routes - Windwood Drive and Leslie Pfeiffer.
Again, with a little luck with weather and equipment we won't be at it all weekend and folks can return to normal well before Monday morning.
When work is done for the weekend the intersection of Fair Oaks Parkway and the westbound frontage road of I-10 will be skewed quite a bit. That skew will continue until the project is finished and traffic is on the new bridge.
August 25-28
This one is the big'un.
We'll have all main lanes of I-10 closed - both directions, to be clear - beginning 9 p.m. August 25 until 5 a.m. August 28. This is the weekend we're demolishing the old Fair Oaks Parkway overpass bridge.
Traffic will use the same detour path we've used before with two lanes exiting the highway in each direction, then re-entering after the intersection. We've seen this work well for us thus far.
Please don't expect this work to wrap up so early the way it did during other closures, though. Demolishing a bridge takes a while - it's an involved process. First crews will lay down a bed of sand or dirt under the bridge. This ensures falling concrete chunks don't do significant damage to the roadway underneath. The bridge is cut and broken into pieces and hauled off in as controlled a manner as possible. Getting trucks into and out of the closure area can be difficult as well, and slow some of the work. We have contingency plans in place, but this can slog things a bit.
Once the bridge is wrecked and pieces hauled out we have to clean up the road, including that bed of sand, and inspect the road surface to ensure we don't have any major damage. Once our inspectors are satisfied the road is traffic-worthy everything opens up and is back to normal.
It's an involved process and will certainly take the entirety of the weekend.
Looking beyond
For those keeping tabs these are the third and fourth major closures at this location. When the project began we anticipated about ten such closures - which means we're about halfway through the misery. The next major closure won't come until we are ready to hang beams - and in order to do that we have a lot of concrete work to do. The likelihood of setting those beams before the end of 2017 is pretty slim, unless RELMCo really speeds up their processes.
One of those ten remaining closures - and likely the final closure - will mirror what we're doing August 18-21 to get the intersection rebuilt and traffic into its final configuration.
Still on schedule
By the way, this project is still on schedule to wrap up by summer 2018.

We're still setting the work zone on US 281

The US 281 expansion has thus far meant restriping travel lanes and clearing the right-of-way. In coming days temporary concrete barriers will go up to allow crews to safely clear brush and other items separate from active traffic.
This requires continued overnight closures between 9 p.m. and 5 a.m. We do this at night to minimize traffic impact on drivers and businesses.
These specific locations will be impacted next week:
  • August 14 at 9 p.m. until August 15 at 5 a.m. Single right lane closure of southbound US 281 from Encino Rio to Redland Road.
  • August 15 at 9 p.m. until August 16 at 5 a.m. Single right lane closure of southbound US 281 from Redland Road to Agora Palms Drive.
  • August 16 at 9 p.m. until August 17 at 5 a.m. Single right lane closure of southbound US 281 from the Loop 1604/Sonterra Road exit ramp to Sonterra Road entrance ramp – please note there will be no impacts to the ramp.
  • August 17 at 9 p.m. until August 18 at 5 a.m. Single left lane closure of southbound US 281 frontage road near Sonterra Road.
Please note that all lane closures are weather permitting and subject to change. To get the most up-to-date information please follow us on Twitter or sign up for email alerts.

FM 1103 bridge starts this week

Edit: due to weather impacts and some scheduling conflicts the start date has been pushed further than expected. Blog below has been updated with the new start date.


A $7.2 million project expanding the FM 1103 bridge over I-35 in Schertz starts the night of September 5 and will wrap up by spring 2019.
Local company Anderson Columbia won the contract to make the bridge five lanes wide (plus turnarounds) and will be churning through a six-day workweek to finish construction as fast as possible.

What's being done
The existing bridge has two lanes; the new
bridge will have five plus turnarounds.
The incredible growth in Schertz and Cibolo has overwhelmed the old two-lane bridge (and, quite honestly, FM 1103 itself ... but there's a whole other post dedicated to that issue).
The new bridge will have five lanes with priority given to getting traffic off FM 1103 headed toward San Antonio. Two eastbound lanes will include one through lane and one optional lane. Three westbound lanes will include a left-only lane, an optional lane and a through lane getting traffic onto Hubertus Road (which is also growing...). Turnarounds will be built on each side of the new bridge.
All this work should position the intersection to appropriately meet the demands of the growing suburban communities depending on this location so heavily.
Oh, yeah, and we'll also upgrade the traffic signals and pedestrian facilities while we're out there.

Getting from here to there
Our biggest priority is minimizing the impact on daily traffic through the duration of construction. That's what our aim is with every project, in fact.
The first thing the good folks of Anderson Columbia will be working on is the new westbound portion of the bridge, including the south-to-north turnaround. That first half of the bridge should be finished before summer 2018.
At that point traffic will be moved onto the new half of the bridge and the existing bridge will be torn out. The eastbound portion of the bridge and the north-to-south turnaround will be built. During this phase of work the bridge will serve westbound traffic only. Those who would use the eastbound portion of the bridge will need to head south to FM 2252, turn around and return to the intersection.

The long detour
First ... why would we do something like this when we work so hard to minimize impact? Traffic data shows the largest demand on the bridge - by far - is the westbound side. This arrangement will actually relieve traffic issues in the area today long before the bridge is complete. It's not something we would typically do, but our engineers believe this is the right way to go.
The duration for this traffic arrangement is expected to last more than six months - not an indefinite length by any means, but certainly long enough to warrant folks gearing up for this.
Remember this will begin before the start of summer 2018, and likely wrap up around the end of the year.

Shorter detours
Everyday work activities will be done mostly behind concrete barricades without disrupting traffic. This is an around-the-clock operation, so expect crews to be out there 24 hours a day, six days a week.
Major closures will be limited to nights and, on occasion, weekends. The weekend closures will come as we need to hang support beams and demolish the existing bridge. Those closures will be announced with at least two weeks' notice.

Traffic switch coming: SB I-410 to Hwy 151

*UPDATE: Dates of traffic shift were changed to August 9-10.


Let's get one thing out of the way first: this is not the final configuration for traffic traveling from southbound I-410 to Hwy 151. The new direct connector to westbound Hwy 151 is not yet opening.
All that said, those who exit southbound I-410 to reach Hwy 151 as part of their daily commutes are about to see a significant change to their routes next week with the completion of what's being called by project staff the "Military Drive Bypass".

What's a bypass and why is it being built?
The bridge that's opening to make this traffic shift possible is a permanent intersection bypass guiding a single lane of frontage road traffic over Military Drive, skipping the traffic signal completely.
We have a few other bypasses - though with much larger capacity - along I-410 on the north side of down, most notably at San Pedro.
The reason for this bypass is access to the Westover Marketplace commercial center. When the new direct connector is built the old ramp, which also serves traffic headed to the shops at Westover, will no longer be in service.
Actually, that old ramp will go much sooner.

A look at the bypass that'll be in play midweek next week.

Current ramp is closing The current ramp serving traffic to Hwy 151 (and the marketplace) will permanently close the night of Wednesday, August 9. That means Thursday's commute will be a bit different - so pay attention!
With the old ramp closed Williams Brothers Construction will be working hard to finish the tie-in to the new direct connector while also looking to improve the capacity of the frontage road as fast as they can.

New ramp is opening
The new ramp for those headed to Hwy 151 will be the ramp folks are currently using for Military Drive. That lane will be guided up and over Military Drive and then follow the same route traffic runs today.
In the near future the new Military Drive exit ramp will open (north of Leon Creek) and we'll change things a bit again.

Planned closures
Before we get to where all this new stuff is in place we'll have a series of overnight closures the first half of next week. The main lanes won't be impacted too much, but expect to see more major closures on the frontage road Tuesday night as traffic is switched.
For those looking to reach Hwy 151 overnight, try exiting Marbach and turning around to reach your destination. It will be slow going, but you should be able to get through just fine.

Overall completion
The big question is pretty clear - and the answer is pretty simple. Overall completion for this project is coming fall 2018.
