I-35 Capital Express Central

Project Description

The I-35 Capital Express Central project is located in the central region of the Austin metropolitan area for a distance of approximately 8 miles along I-35 between US 290 East and SH 71/Ben White Boulevard.

The proposed improvements include removing the existing I-35 decks, lowering the roadway, and adding two non-tolled high-occupancy vehicle managed lanes in each direction along I-35 from US 290 East to SH 71/Ben White Boulevard. The project will also reconstruct east-west cross-street bridges, add pedestrian and bicycle paths, and make additional safety and mobility improvements within the project limits.

Here is a video with updates to proposed improvements since the August 10, 2021 open house: Capital Express Central – Modified Alternatives Overview

Environmental Study

TxDOT completed the most rigorous level of environmental analysis with the development of an Environmental Impact Statement (EIS) for the I-35 Capital Express Central project.

You can review the draft Environmental Impact Statement (DEIS). You can also find information from our recent public hearing here.

You can review the Final Environmental Impact Statement (FEIS) and Record of Decision (ROD) here.

The timeline below illustrates where we are in the process. For more information, please check out the Environmental Study page.

As a part of the I-35 Capital Express Central project, TxDOT is proposing a complete reconstruction of the Lady Bird Lake bridge. To learn more about the construction of this portion of the corridor, along with anticipated trail impacts, click here.
