Burst water main floods Bay Bridge lanes in Treasure Island tunnel

By Carlos E. Castañeda

A water main break in the Treasure Island tunnel of the San Francisco-Oakland Bay Bridge has flooded some eastbound lanes just ahead of the afternoon commute Tuesday.

The California Highway Patrol said in a traffic alert at 1:43 p.m. that the water main break above the eastbound lanes inside the tunnel prompted the closure of the number 4 and 5 lanes.

Caltrans and the San Francisco Fire Department were at the scene attempting to resolve the incident, the CHP said.

As of 2:22 p.m., the CHP said all lanes had reopened.

There was no immediate word on what caused the water main break.
