Overview
- The California Highway Patrol reported at about 1:43 p.m. Tuesday that a burst water main inside the Treasure Island tunnel flooded the eastbound roadway and closed lanes 4 and 5.
- Caltrans crews and San Francisco Fire Department units responded in the tunnel to manage the flooding and start repairs.
- CHP later said all eastbound lanes on Interstate 80 through the tunnel had reopened.
- Officials did not share how long the closure lasted.
- The Bay Bridge carries heavy commute traffic for the region, so even two blocked lanes can quickly slow thousands of drivers.
