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.
