I-35 Construction Begins, Impacts Lady Bird Lake, Trails, Austin Parks

The Texas Department of Transportation (TxDOT) is set to begin a multi-year construction project on Interstate 35 through downtown Austin that will significantly impact access to Lady Bird Lake, the Ann and Roy Butler Hike-and-Bike Trail, and several city parks starting August 10, 2025. The project, which aims to reduce congestion by expanding I-35, will last until 2033 and involve rerouting trails, intermittent closures of the hike-and-bike trail for up to seven days at a time, and restrictions on boating and other activities near the bridges. Key affected locations include Edward Rendon Sr. Park, Waller Beach, Chicano Park, and Norwood Dog Park, with some areas facing partial or complete closures and the removal of several trees. While TxDOT plans to maintain safety and provide ADA-accessible detours, there will be no official detour during some closures, requiring pedestrians to take longer routes. Coordination between TxDOT, the Austin Parks and Recreation Department, and The Trail Conservancy continues to address concerns about trail width and accessibility during construction. Public notices and signage will be provided ahead of closures to inform residents and visitors of the ongoing changes.
