There’s a map for that: Know when to avoid I-35

TxDOT's new map will help drivers know when to avoid I-35.

TxDOT's new map will help drivers know when to avoid I-35.

With seven projects under construction on I-35 and an eighth starting this spring, the Texas Department of Transportation has launched a new website to aid drivers in the capital area.

The new site,, includes details on upcoming lane closures, traffic incidents and travel delays in Hays, Travis and Williamson counties. Other tools include:

  • an interactive map showing how a construction project affects I-35;

  • alerts to notify drivers of potential issues before they leave;

  • email notifications with lane closures and project updates;

  • social media updates; and

  • construction project information, such as timeline, cost and real-time updates.

TxDOT has more than 40 projects ultimately planned to improve I-35, although many remain unfunded. The agency has been constructing projects by piecemeal as funding becomes available. Most funding identified thus far has come from state propositions 1 and 7 that diverted more state funding to state roadways.

Active I-35 projects include:

  • RM 1431-FM 3406: Two ramps on southbound I-35 will be reconstructed and reversed.

  • FM 3406: The frontage roads will be improved, and the bridge over I-35 will be rebuilt.

  • US 79-SH 45 N.: Braided ramps, where one ramp crosses over another, will be built on the northbound mainlanes, and the intersections at US 79 and I-35 will be reconstructed to include a third left-turn lane from westbound US 79.

  • 51st Street: A southbound intersection bypass lane will be added, and the entrance/exit ramps will be reconfigured. Bicycle and pedestrian facilities also will be added.

  • Oltorf Street: The bridge will be rebuilt, and the entrance/exit ramps and frontage roads will be improved. New U-turns will be added as well as bicycle and pedestrian enhancements.

  • Stassney Lane-William Cannon Drive: The frontage road bridges over Williamson Creek and the bridges at Stassney and William Cannon will be rebuilt. The I-35 mainlanes will be widened with shoulders and extended entrance/exit lanes. U-turns will be added as well as bicycle and pedestrian facilities.

  • Slaughter Creek overpass: The bridge will be replaced and a southbound to northbound U-turn bridge will be added. The project includes widening the southbound frontage road to two lanes and added safety lighting.

  • RM 150-Blanco River: One new ramp will be added and five existing entrance/exit ramps will be modified.
