Major closures this weekend on I-10 East ... why?

Drivers have probably noticed more activity, including recent lane switches around the new Woodlake Overpass the past few weeks. Texas Sterling Construction is working hard to complete this new intersection for local residents.


Once built this intersection will particularly benefit those using Woodlake Parkway on a daily basis. Drivers will have better access into and out of the neighborhood. Driving time will improve with new turnarounds. The new intersection will improve the overall flow of traffic and even open up opportunities for future expansion of Woodlake Parkway to the south.


The new Woodlake intersection is expected to be complete by end of the summer.


Ramp Reconfigurations… they can’t come fast enough.
We have heard your concerns about the backup onto the main lanes and we appreciate your patience on this one.


Texas Sterling Construction has been working with utility partners to speed up the ramp reconfigurations. As of now, the contractor is building the outside lanes of the frontage roads. Once they finish they will move to the inside lanes. That's when crews will tie the new ramps to the frontage roads.


We’re hoping that can all happen this summer. We know summer sounds a long time from now, but it will be here before we know it.


Upcoming lane closures
Texas Sterling Construction will set beams for the turnaround at Foster Road this weekend. This requires closing the main lanes of I-10 at Foster Road. That work will start by 7:00 a.m. Saturday, February 17; lanes will reopen no later than 5:00 a.m. Monday, February 19.


The detour is pretty simple. Traffic will exit Foster Road, continue along the frontage road and re-enter at the next available ramp. We'll have officers controlling traffic at the intersections to help things keep moving. Despite our best efforts you should expect delays if you’re driving this section of I-10 this weekend.


As always, drive friendly when you see those construction zone signs. The weather has been cold and rainy the last couple of days, so take this as a friendly reminder to use caution - especially in construction zones.


About the project
The $63.8 million I-10 East project started Fall 2016 and is expected to wrap-up mid-2019. Texas Sterling Construction is the contractor along with CEC as the project management and inspection team. Improvements include: new bridge at Woodlake Parkway, intersection upgrades, new signals, reconfiguration of entrance/exit ramps and conversion of the frontage roads. You can read all the details about the project here.

A new victory in the battle against wrong-way drivers

Monday afternoon, just after the lunch hour, a high-priority alert jostled the attention of a pair of engineers and an operator at our TransGuide operations center. Photographs attached to the alert showed a white pickup truck hastily driving the wrong way across the Callaghan Road exit ramp on US Hwy 90.

The alert is part of a new system we are testing to combat the growing problem of wrong-way drivers in San Antonio. Since we joined the San Antonio Police Department to track wrong-way driving incidents in 2011 we've seen an average of more than 460 wrong-way drivers reported on local highways.
You read that correctly. More than 460 wrong-way driver reports per year.

This heat map shows the hot spots of
wrong-way driving activity, 2017
Even more frightening than the frequency of these events is the growing prevalence. In 2013 we saw 381 reported incidents; we had 575 such events reported in 2016. In order for these events to count they must take place on a controlled-access highway, or what most people would call a freeway.

Some of the events work themselves out: the driver realizes the situation and turns around. Some end with handcuffs. Others end in tragedy.

That's how the wrong-way driver reported the morning of March 16, 2011, turned out. Christopher David Baldaramos, who was 31 at the time and on probation for a DWI charge the previous year, was driving north in the southbound lanes of I-35 downtown without headlights. San Antonio Police Officer Stephanie Ann Brown, then just 27, was driving south to answer a call for an officer in trouble and was unaware of Baldaramos. He drove his SUV head-on into Brown's patrol car. Baldaramos was pronounced dead at the scene; Brown died less than an hour later at the hospital.

Within two months a task force was assembled in Brown's honor. Its mission is simple: prevent wrong-way fatalities. Its efforts have garnered nationwide attention. Because of the taskforce's efforts we've installed LED-lit "Wrong Way" signs across the city, making the specialty sign standard for all future highway projects. Public awareness campaigns have launched to combat drunken driving - the leading factor in wrong-way driving incidents. By the end of 2013 special radar-detection systems were installed at select locations along US 281 north of downtown.

Each step taken has led to another. The latest step - installing WrongWayAlert detection systems on a handful of ramps along US Hwy 90 at the start of the year - came when the detection systems along US 281 proved ineffective. The previous systems used a single detection point and would often provide false positives, rendering the system ineffective. It also failed to provide a point of origin for the wrong-way driver, only detecting the threat once it was on the highway.

The new system uses three detection points, triangulating objects being detected to give the system the ability to know precisely when - and where - a wrong-way driver enters the highway.

The moment an issue is spotted WrongWayAlert, a system developed by the company to manufacture the first radar speed signs back in 2001, sends a text message to a dedicated phone a the TransGuide center and issues email alerts to mailboxes we keep open around the clock. Our operator is able to pass the alert along to a police dispatcher sitting less than a dozen feet away while simultaneously finding the culprit on one of more than 200 traffic cameras across the city.

Together the TransGuide operator and the police dispatcher then guide responding officers to the driver to assess the situation and make arrests if needed.

Four ramps, all along US 90 on the city's West Side, have been equipped with the new gear thus far, with another dozen or so planned as we pilot the system. If Monday's ping is an indicator of performance it won't be long before we have WrongWayAlert running across the city.

The truck detected Monday turned out to be a construction vehicle traveling safely through the work zone. The time it spent on the ramp was no more than one or two seconds before it was safely back behind barrier. TransGuide engineer John Gianotti says the detection of this truck was actually remarkable and boosted confidence in the new system. After all, actual wrong-way drivers will be on these ramps a much longer duration (between five and ten seconds) to allow the system to see and create an alert.

Mail Bag: revisiting old answers, Ralph Fair Road, Fair Oaks Pkwy and more

Great work keeping the blog updated and providing great information!
Two questions: in the last mailbag there was a question about I-35 at Walzem reducing down to three lanes in each direction then opening up to four lanes.
You wrote that it is supposed to be four lanes but it is still three lanes each direction; any idea when that is supposed to be complete? (I know the weather hasn’t cooperated).
Second; I read the post regarding stop lights and what it takes to install (namely cost) and have a new respect before ‘firing from the hip’ saying every intersection that causes me a few seconds of inconvenience needs one. However, there is one intersection that, I think, is overdue for another look — Foster Rd and FM 1346. I’ve seen eastbound traffic back up all the way where the two lanes merge into one. Any plans for a traffic light there in the near future? The four-way stop seems very outdated.
And a comment about the 35 project— it rocks! You guys kicked its [expletive]!
Thanks again for the great information and posts! The person that keeps this updated does a fantastic job!
- Todd
First of all, flattery will get you ... well, pretty much anything. Thanks so much! Sorry we had to edit your comment a bit. This is a family blog, after all!
To your first question ... we were fully wrong about I-35 being opened up earlier. We were operating on old information and got it wrong. Instead of opening in January, it actually opened up to the new capacity last week and you are (hopefully) enjoying that extra lane each direction. We learned from the experience and will add extra verification with guys in the field before posting things in the future.
As for the second question, the best we can do is put the location on our list to be studied. You're not the first to ask, and we did recently upgrade that intersection with flashing yellow lights. We have to go with the hard data, so we'll see what things look like once we've done a warrant study.


I’ve been noticing some closures overnight at the Scenic Loop and I-10 overpass in Boerne so crews can law pavement underneath. This is exit 543, not the Leon Springs overpass at Boerne Stage Road. I’m not sure if these are being posted under the “Boerne” or “Leon Springs” categories, but I haven’t seen these particular closures in the weekly posts. Am I missing something? I live by this particular overpass and the detours are pretty far out of the way if we can’t go under the freeway.
- Grant
These should actually be posted under "Other Roads - Boerne". Because it's actually Scenic Loop Road, not I-10, that's closed it goes under a bit of its own heading.
The detour for this one is pretty simple - simply head down to Balcones Creek, cross over and turn around, then come back. The whole thing is about three miles.


Regarding Gold Canyon Exit at 1604, thanks for the quick response.
This same setup occurs on eastbound 1604 at the exits for 281 north and south. Two normal lanes and an auxiliary lane. That auxiliary lane terminates with the exit for 281 South. However, prior to that termination there is an exit for 281 North. If this is an unsafe condition, why is it allowed for this area but not for Gold Canyon?
- Marshall
The two areas actually aren't the same at all. Here's a look at the Gold Canyon area you're asking about:
Note the auxiliary lane stretches less than half a mile (the orange line is the auxiliary lane) and encounters both an entrance ramp, with traffic trying to enter the highway and weave onto the main lanes, and an exit ramp, with traffic weaving off the highway. We've also got a bridge in the middle of everything, limiting what we can do here.
Now, here's a look at eastbound Loop 1604:
You'll have to click on this one to blow it up a bit, it's not the same scale. Why? Because it's a significantly longer stretch of roadway we're trying to fit in the same column width in the blog. The auxiliary lane to which you're referring is well over a half-mile - and it doesn't feature the conflict of entering and exiting traffic. It's also lacking that pesky bridge in the middle.
If we were to stretch it out to capture the conflict of entering traffic with these two exit ramps, by the way, the stretch would be nearly a full mile.
Remember, that Gold Canyon area is well under a half-mile. The distance between these two exit ramps alone is more than what you've got at Gold Canyon.
That's why the situation you see on eastbound Loop 1604 approaching US 281 is safe and an extra ramp on westbound Loop 1604 near Gold Canyon would not be.


My wife and I think a 'fly over' from Ralph Fair to (eastbound) I-10 and from (westbound) I-10 to Ralph Fair would increase the functionality of both roadways. I know it would be expensive but sooner would be cheaper than later. This is going to have to be addressed due to the population explosion in eastern Kendall County. Is anything like that in the works? Thank you.
- Marcial

One thing you're not seeing (yet) is the huge benefit that new intersection at Old Fredericksburg Road will be to the intersection at Ralph Fair Road. All those folks in that new development along Old Fred Road that's now pushing through the Ralph Fair intersection will be removed from the traffic equation completely.
Just hang tight a few more months, you'll see what's happening and you'll be glad we didn't go in with a direct connector and it's quarter-billion-dollar price tag. Everything we've had going the last few years has been part of an overall plan to address the growth, and we're just about finished.
For the record ... no, we don't have one planned at this location, either. It's doubtful we'll ever get to that sort of situation. Frankly, we need direct connectors at Loop 1604 and I-10 or at Loop 1604 and I-35 first.


It is encouraging to see the progress on I-10 north of 1604. The progress seems to end at Dominion Drive however. What is the expected completion date of this interstate expansion and scope (distance) to be included?
- Dugald
We're glad we're encouraging! The expansion will add two lanes in each direction between La Cantera Parkway and Ralph Fair Road. We're scheduled to finish around the end of 2020. You'll see a new lane in each direction ready to use in 2019, though.


Please add me to your email list for traffic updates.
- Tami
We actually don't keep an email list. Your best bet is to subscribe to email alerts on our blog, which can be done by entering your email in the subscription bar on the left, and you'll get notices every time we post something.


Can you send me a picture of what the intersection at Fair Oaks parkway and I-10 will look like when completed.
- Chuck
All of that is posted online, Chuck. Take a look here.


What is going on with UTSA Blvd near UTEX Blvd? The expansion project from three lanes to five lanes looked complete in the Fall. Then after a few weeks, crews tore up the new surface for half of the new lanes for what looked like drainage work. It's been like that for about three months now with very little activity. This back-to-one-lane-each-way thing is frustrating after getting to use the expanded lanes.
- John
You're one of a growing list of folks asking us, John. We'll tell you what we told the others: that's all part of a private commercial development and they're moving around some utility stuff. We are pretty sure all the work is being done for Security Services FCU, who is developing that whole area along the road heading toward I-10.
We don't have any real oversight with them; as long as the traffic control is set up in line with standards in our Manual for Uniform Traffic Control Devices (it is), they're fine to be out there and we have no tools available to spur them along.

US 281 expansion - the road behind, the road ahead (for 2018)

Can you believe we are already nearing the end of January 2018? As we get acquainted with the new year and all that it has in store, let’s take a look back to see what we accomplished in 2017 on the US 281 expansion between Loop 1604 and Stone Oak Parkway.
Construction began on phase I during the summer of 2017 and motorists began seeing construction activities right away, including:

Columns placed in the early stages of Loop 1604
direct connector construction
  • Construction of frontage road bridges at Mud Creek
  • Completion of bridge support columns and foundations for two of the four direct connectors to Loop 1604
  • Start of construction for retaining walls between Sonterra Boulevard and Redland Road

We do not expect to slow down this year. We should be finished with our first stage of work by the end of the year. In order to get there we will:
  • Construct the new frontage roads outside the existing US 281 travel lanes
  • Work on all four direct connectors
  • Utility adjustments – so many utility adjustments!
  • Drainage work
  • Install sound walls, bridges and retaining walls where planned
  • Construct the sidewalk
Construction crews work on the footprint of the
northbound frontage road near Sonterra Boulevard
Our next stage is scheduled to start late 2018 and will switch traffic to the newly constructed frontage roads. This will allow crews to build out the new express lanes.
By breaking construction into these two stages we can minimize traffic impacts and maintain the same level of service you now enjoy. Even when traffic is moved to the frontage roads we will maintain the superstreet configuration.
The construction team is dedicated to mitigating traffic, access and neighborhood impacts as much as possible. To continue to stay up-to-date on construction activities and lane closures sign up to receive email notifications here.
Overall project completion is slated for 2021.
