Welcome to the MoPac South Environmental Study

The MoPac Expressway south of Cesar Chavez Street provides a critical link to downtown Austin and other major highways such as US 290 and Loop 360. Consistently ranked as one of Texas' 100 most congested roadways (Texas A&M Transportation Institute, 2020), it attracts up to 179,000 cars and trucks per day. Expanding population, as well as residential, retail and commercial development have led to increased traffic congestion. If we do nothing to address congestion, drivers could spend an additional 35 minutes traveling the corridor by 2035.

In 2013, the Mobility Authority and TxDOT initiated an Environmental Study to identify a solution that improves safety and mobility for drivers, transit riders, bicyclists and pedestrians in a manner that promotes environmental stewardship and sustainability. 

The Express Lane(s) Alternative has been identified as the Reasonable Build Alternative because it best meets the project’s Purpose and Need. The express lane on MoPac from Cesar Chavez Street to Parmer Lane has proven effective. Since opening in 2017, it has reduced travel times, increased use of transit, and created an option for more reliable travel on the north MoPac corridor.
