Welcome to the MoPac South Environmental Study

This environmental study has until recently been on hold due to a lawsuit. Look for future movement on this proposed express lanes project in 2018. Sign up for updates here.

The MoPac corridor south of Cesar Chavez Street is a vital artery for Austin commuters and neighbors, as well as visitors to our region. Constructed between 1975 and 1992 as a four to six lane divided highway, it attracts up to 130,000 cars and trucks per day. Over time, population growth and development have increased and are negatively impacting the quality of life for corridor travelers.

In 2013, the Mobility Authority and TxDOT initiated an Environmental Study of the MoPac corridor from Cesar Chavez Street to Slaughter Lane. We are working with Capital Metro and other local partners to improve safety and mobility for drivers, transit riders, bicyclists and pedestrians in a manner that promotes environmental stewardship and sustainability.
