I-35 Capital Express North: 2026 Status, Cost, Route Map & Timeline
The i-35 capital express north project is a major highway expansion spanning 11.5 mi along Interstate 35 from SH 45 North to US 290 East in Travis and Williamson counties, Texas. Spearheaded by TxDOT, this $606M brownfield reconstruction initiative is funded through state and federal transportation programs to alleviate congestion across the Austin metropolitan region. Designed to improve mobility, the project adds one non-tolled high-occupancy vehicle managed lane in each direction, reconstructs key bridges, builds bypass lanes, and enhances bicycle and pedestrian infrastructure along the corridor. Following extensive environmental review and right-of-way coordination, official plans establish a strategic alignment that integrates modern traffic management systems with existing regional transportation hubs. Construction officially broke ground in early 2023, with an anticipated completion date targeted for late 2028. Updated route map details highlight major improvements near Wells Branch Parkway, Parmer Lane, and Braker Lane to ensure long-term regional connectivity.
