Heads up Bay Area: the Bay Bridge will likely be shut down on President's Day weekend.
The closure will only impact westbound lanes and is needed to prepare for the planned opening of the new Eastern span.
Caltrans said the two- to three-day closure will start Saturday Feb. 18 and may last through the Monday holiday.
The project is weather permitting, so if it rains, the bridge will not have to close.
California Department of Transportation spokesman Bart Ney says the hours haven't been set, and he notes rain could postpone the closure or lengthen it.
Caltrans needs to close the westbound lanes of the bridge to allow construction crews to reconfigure the roadway and re-stripe lanes.
Caltrans is discussing alternative travel plans with BART and ferry services.
