SR 539/Bay-Lyn Dr to International Boundary - Corridor Improvements

The SR 539 border crossing is currently open for daytime crossings only. The planned switch to a 24/7 border crossing operation will increase congestion on the SR 539 corridor between SR 546 and the International Boundary. Constructing a four-lane divided highway will improve mobility, reduce the risk of collisions, and facilitate freight movement across the international border. As of February 01, 2023, this project is in Conceptual status. Preliminary engineering has begun and environmental design is expected to be complete in the Third quarter of 2024. The contract advertisement is expected in First quarter of 2026 and construction is anticipated to be operationally complete in the Fourth quarter of 2027.
