ABOUT THE PROJECT

The San Bernardino County Transportation Authority (SBCTA), California Department of Transportation (Caltrans), and the City of Colton have partnered to improve Mt. Vernon Avenue over Interstate 10 (I-10). The project will enhance circulation and mobility along Mt. Vernon Avenue between East Valley Boulevard to the north and the I-10 eastbound ramps/Mt. Vernon Avenue intersection to the south.



Improvements include replacing and widening the existing Mt. Vernon Avenue bridge over I-10, upgrading roadway and intersection operations, and enhancing bicycle and pedestrian facilities through the interchange. The project will also provide Americans with Disabilities Act (ADA) compliant curb ramps, crossing activators, and tactile warning surfaces at intersections where crosswalks are included.

These upgrades will help reduce local congestion, improve safety for all users, and support future transportation improvements in the corridor, including planned I-10 Express Lanes.
