Highway 1 will close in both directions tonight from Lake Street to Highway 101 in San Francisco.
The closure from 8 p.m. tonight to 11 a.m. Sunday morning will allow work crews to shift northbound and southbound traffic to a new two-lane bridge on Park Presidio Boulevard, north of the MacArthur Tunnel, as part of a project to replace Doyle Drive, project spokeswoman Molly Graham said.
Workers will also restore the exit from southbound Highway 101 to Highway 1/Park Presidio to two lanes.
Northbound drivers will be detoured via Geary Boulevard to Van Ness and Lombard Street, while southbound drivers will be directed to continue on Highway 101 to Geary Boulevard to Park Presidio.
