Caltrans officials said Monday that emergency repair work on a crack found on the Bay Bridge will not be completed by 5:00 a.m. Tuesday, and are advising drivers to prepare alternate plans for the morning commute.

Transit officials say the San Francisco-Oakland Bay Bridge will not reopen in time for the Tuesday morning commute.

The announcement late Monday leaves thousands of drivers to find alternate ways to get into San Francisco and sets the stage for possible gridlock on other San Francisco Bay area bridges and roads.

California Department of Transportation director Randy Iwasaki said workers will not be able to complete work to repair a crack in the span by Tuesday 5 a.m., when the bridge was scheduled to reopen.

The bridge was shut down over the holiday weekend so a section of the eastern span could be cut out and replaced with a new double deck section as part of a seismic upgrade. Crews used the closure to inspect the bridge, discovering the crack Saturday.
