Overnight closure of Golden Gate Bridge off-ramp Wednesday, Thursday

The last northbound exit for drivers on U.S. Highway 101 before they get to the Golden Gate Bridge will be closed Wednesday night and again on Thursday as part of the ongoing construction project to rebuild Doyle Drive, transit officials said.

Between 10 p.m. Wednesday and 5 a.m. Thursday, crews will be shutting down the off-ramp, which leads to the bridge's southeast visitor plaza as well as Lincoln Boulevard and Merchant Road.

The off-ramp will be closed again from 10 p.m. Thursday to 5 a.m. Friday.

During the closures, crews will be improving traffic conditions in the area by widening the off-ramp to create separate left and right turn lanes, implementing an all-way stop at the intersection of Lincoln Boulevard and Merchant Road, among other changes, transit officials said.

Drivers are asked to use local roads to access Lincoln Boulevard while the off-ramp is closed.

The closures are part of a years-long project to replace Doyle Drive, a seismically unsafe portion of Highway 101 in the Presidio on the northern edge of San Francisco.

The project is a partnership between the Golden Gate Bridge, Highway and Transportation District, the National Park Service and the Presidio Trust.

The new roadway, which will be called the Presidio Parkway, is expected to open in 2015.
