Over the course of the next month, the Texas Department of Transportation will be fielding public comments on what future improvements along stretches of I-35 in North Austin should look like.

TxDOT has opened a digital open house through June 10 for the I-35 Capital Express North project. Residents can review materials for the project and leave feedback on the scope and implementation of the proposed overhaul through the website TxDOT has set up for this virtual open house.

The I-35 Capital Express project is a massive overhaul of I-35 through the Austin area, stretching from Round Rock to Buda. The northern section will run a 10-mile stretch from US 290 East in North Austin up to SH 45 N in Round Rock and is projected to cost $400 million.

According to presentation documents from TxDOT, the I-35 Capital Express North section will add one nontolled high-occupancy vehicle lane in each direction from SH 45 N to US 290 East.

Plans for the project also currently include improvements for pedestrians and cyclists, with more than 15 miles of new shared-use sidewalks proposed along the I-35 frontage road in each direction.

The state also plans to reconstruct six bridges throughout this section of the project and will build a new diverging diamond intersection at Wells Branch Parkway.

TxDOT is currently finishing construction of a similar diverging diamond intersection in North Austin at I-35 and Parmer Lane. According to the state’s presentation of the project, these intersections are designed for intersections with a high volume of left-turning traffic.

If the state stays on its projected timeline, construction may start on parts of the I-35 Capital Express North as soon as 2022.

The public comment period for this project is open through June 10. Residents can submit comments here, email [email protected], leave a comment by voicemail at 512-721-2832 or write to I-35 Capital Express North Project, Attn: Michelle Cooper, P.E., 1608 W. Sixth St., Austin, TX, 78703.
