Are the lanes of I-10 west of town really that narrow?

We've had more than a few folks call, email or otherwise ask us about the lane widths on I-10 between La Cantera Parkway and Ralph Fair Road, where we're adding two lanes in each direction.
 
Just how wide are the lanes?
Throughout the construction zone lanes are set at a typical standard of 12 feet wide with a minimum separation between the edge of the lane and the concrete barrier of one foot, measured from the inside edge of the lane line.
That's the typical width of the highway lanes. In a few small stretches of the construction zone the travel lanes are reduced to 11 feet while maintaining the one-foot separation to the concrete barrier. For reference, most vehicles range from five feet wide with small compact cars and seven feet wide with large pickup trucks. Semi trucks are, by federal standard, just over eight feet wide.
By the way, at a height of nearly four feet those concrete barriers tend to tower outside car windows. Some have even commented on how close the barriers feel when driving through. We're all Texans, after all, and we're used to our wide-open spaces. We can’t be blamed for appreciating some elbow room.
You still have that full foot between the edge of the lane and the barrier, though.
 
Why the varying lane widths?
Safety is our top priority. The traffic control plan for this job, which is specific to the project, sets lane widths and standards in the work zone to keep motorists and the work crews safe. Project supervisors are constantly assessing conditions and making approved changes as needed.
One change you may have noticed is the reduced speed limit for the westbound lanes. That 60 MPH limit is not just a construction-zone recommendation. It's enforceable by law enforcement, and you can't simply get out of speeding tickets in work zones by going to traffic school. We've recently set out new speed limit signs equipped with radar and an LED reader board showing drivers their own speed to help drivers obey the new speed limit.

What’s up next for the project?
  • Crews will continue the placement of storm sewer facilities
  • Drill shaft boring at Camp Bullis bridges will take place in the next couple of weeks
  • Construction of bent caps at Dominion bridge will occur
  • Placement of asphalt bond breaker between the eastbound and westbound main lanes will be added

Mail Bag: I-10 frontage roads at Old Fred, signal timing, enforcement and more

Can you please explain the multiple construction delays that have occurred at Old Fredericksburg Rd and I-10 frontage Road. It was closed in October and targeted for December and had been delayed now for the 3rd time to March! How does this now take 6 months to add drainage?! Yes we’ve had rain, ice, and snow days but not for 4 months straight. This detour has been a major pain to get around for those that live in neighborhoods off the frontage roads.
- Christina
Please clarify how 4-6 days of inclement weather would cause a completion date to be extended over 90 days? Original completion was to be Dec 23.

- Vicky
We'll pull no punches here. We went directly to the contractor to find out what is going on and to let them know of the danger they're in of having their reputation in the public harmed.
Back in December Sundt's area director said they were going to work hard to get the road reopened to two-way traffic. At that time the items to get constructed before the frontage road could be reopened included a culvert and headwall, dirt work to develop the two roadway lanes and laying asphalt, curb and sidewalk. That road surface was to be wide enough for barrier so they could continue to work on a retaining wall.
At the time Sundt said they could get all that done in about 5-6 weeks, not including the mandatory break over Christmas. After adding the likelihood of inclement weather their assessment showed a completion of mid- to late-February.
So much for that idea. Here's what they said mid-February in an email update:
"Obviously, we did not make the second or third week in February to open up the westbound frontage road. We left the (storm water detention) pond construction out of the prior list on what needs to be done before the paving can go in. The access is really tight as well for the wall construction."
These are the two biggest reasons they're giving us for the delay. The lesson we're learning on our end is the need for milestones on work like this; we left the milestone off during planning as a judgment call believing the intersection would be built quickly as it was broken into quadrants. That omission won't happen in the future.
As for now, Sundt is working on that retaining wall and the pond, as well as the culvert that was being built. They have brought in two additional concrete crews to get the concrete work moving faster. Pavement work needs to wait a bit for dry weather as well as these other tasks to wrap up.
From Sundt's area manager: "We are making this corner of the intersection a priority on the job, but there is just a lot to take care of."
At the time of the email update we got a rough estimate on when Sundt would have things wrapped up. In that note they estimated:
  • Retaining wall, three more weeks
  • Concrete pads lining the pond, two more weeks
  • Concrete channel for the box culvert, two more weeks
  • Road grading and asphalt work, two weeks (cannot begin until wall and pond are finished)
  • Concrete curb, sidewalks and island, two weeks (cannot start until after the road grading and asphalt work is done)
  • Best-case scenario is to get two-way traffic reopened by March 21
Sundt isn't making the corner a priority just for fun, either. At this point they need to finish in order to do other work. As soon as they have that southeast corner of the future intersection of Old Fredericksburg Road and I-10 reopened they'll flip over to the northwest side. They'll then work around to the northeast and then the southwest quadrants. If that sounds painful, here's some assurance from that same area manager:
"These other three quadrants will go much quicker due to roadway pavement reconstruction being the only aspect of work to be done in these areas."
That is, they only have the actual roadway to mess with in the other quadrants - not a ton of drain structures.
Once the intersection is built Sundt will go to work on the new exit and entrance ramps, which need to be in place before we can switch traffic to one-way.


What do orange flags on top of stop sign mean? Thanks
- Anthony
Those are actually there just to make the sign more visible. Check out section 2A.15 in our Manual for Uniform Traffic Control Devices online.


Who is responsible for signal light timing on Loop 1604 near Randolph AFB between Hanover Cove and Lower Seguin Rd? It seems as though the lights are perfectly timed to make you stop at each intersection, almost without fail.
Synchronizing the lights would really help to alleviate traffic buildups here.
- Marshall
Thanks for bringing this issue up, Marshall. Those signals should be ours to time. Keep in mind they're not on a true timer - those days are over. We use instead a video infrared vehicle detection system (VIVD) on those signals, which act as smart devices to trigger the signals when a prescribed volume of traffic hits the intersection from a given direction.
We'll have our traffic operations folks check out those signals to make sure they're operating the way they should.


Just wondering whether anyone enforces the "no trucks in left lane" signs on I-35 north of 1604 through New Braunfels? I drive that section daily and see a truck using the lane at least once a week, sometimes even blocking traffic or cutting off cars. Do you have more information on the purpose of those signs? Thanks for all of your posts!
- John
On any major highway the left lane is primarily for passing. Where semi truck traffic is typically 5-10 miles per hour slower than the rest of the traffic, those trucks shouldn't be in that left lane at all.
Within city limits we can post those. You'll note they are white signs with black writing - regulatory signs. Enforcement is entirely up to the police department patrolling those roads. In the case you're describing, that would be New Braunfels Police Department or the Department of Public Safety (Comal County Sherriff has authority to patrol there, but they don't do it often in an effort to put their resources in areas not covered by the city police or by DPS).
If that doesn't answer the question, let us know and we'll give it a bigger crack!


THANK YOU! To the person(s) who had the idea, and to the person(s) who went out to westbound I-10 (before the Dominion Drive exit) and put a speed reader monitor.
Driving that part of I-10 is frustrating, and disappointing, with the speeders. With reconstruction, no shoulder, and barriers ... the speeding got horrible. Not anymore! People are slowing down! YAY!
- Mercy
We're glad you like those measures! We like to use the speed monitors as safety devices on some of our major projects where highway main lanes are under significant construction, like I-10. We are also using these radar trailers on I-35 near Walzem, and we consider them carefully for each major project as we move through the planning process.

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.
