South Lamar Corridor Improvements

The City of Austin is investing approximately $36 million from the 2016 Mobility Bond on improvements to South Lamar Boulevard between Riverside Drive and US 290. The City expects this to reduce vehicular delay, improve the effectiveness of transit, create continuous ADA-compliant sidewalks and continuous bicycle facilities along the entire length of the corridor. The most up-to-date information can be found on the City's webpage for the South Lamar Corridor project. The following are the City's South Lamar Corridor team contacts:
