Caltrans will again close two ramps south of the Golden Gate Bridge in San Francisco this weekend, the second such closure as crews continue pre-construction for the rebuild of Doyle Drive.
Doyle Drive, the 1.5-mile, raised southern approach to the Golden Gate Bridge, was built in 1936 and has been deemed seismically and structurally deficient. Construction on the new project is slated to begin this fall.
As part of the rebuild, two Doyle Drive/Highway 101 off-ramps leading to southbound state Highway 1 — also known as the Park Presidio and going south through the city to 19th Avenue–will be closed for tree removal.
The closure will take place Saturday and Sunday from 5:30 a.m. to 11:30 a.m. The ramps were previously closed for one weekend in August, and similar closures are planned for Sept. 19, Sept. 20, Sept. 26 and Sept. 27.
Heading south from the toll plaza, the off-ramp to southbound state Highway 1 will be closed, and heading north from the Marina District to the toll plaza, the off-ramp to southbound state Highway 1 will also be closed.
Drivers heading south of the toll plaza and looking to get to Highway 1 will be directed by detour signs to continue on Doyle Drive, take Lombard Street to Van Ness Avenue, and then take Geary Boulevard to Highway 1/19th Avenue.
Drivers heading north toward the toll plaza and seeking to exit onto Highway 1 will be directed past the closed off-ramp to the last exit before the toll plaza, and to take Lincoln Boulevard to 25th Avenue, and then Geary Boulevard to Highway 1/19th Avenue.

Officials hope to complete the new Doyle Drive, to be called the Presidio Parkway, by 2013. The project’s cost has been estimated at $1.05 billion.
