SAN FRANCISCO - Caltrans is conducting routine cable inspection and maintenance on the westbound Interstate 80 (I-80) San Francisco/Oakland Bay Bridge starting September 26, which will require the closures of the far-right lanes from the Yerba Buena Island Tunnel tothe end of the bridge. This project ensures that the bridge remains safe and operational.

Inspections of the cable will be in progress Monday through Friday nights from 8:00 PM to 4:00 AM, until May 2025. A construction work zone speed limit reduction will be in effect during these hours, reducing speed limit to 40MPH. Caltrans will keep the public apprised of all future scheduled closures.
