Second of Three Weekend Closures Scheduled for 19th Avenue (State Route 1) Rehabilitation Project in City of San Francisco

Schedule: 74-hour closure from Friday, May 8 to Monday, May 11 starting at 3 a.m.

San Francisco County - Caltrans is scheduled to begin the second of three weekend closures for the 19th Avenue Rehabilitation Project from Friday, May 8 to Monday, May 11. This is the second phase of the project as the first phase was completed in January 2026.

This second weekend closure paves all lanes on Southbound 19th Avenue from Lincoln Way to Sloat Boulevard, including the Lincoln Way and 19th Ave intersection. Two lanes will be closed with one lane open for public transit, emergency responders, and local access.

Between 3 a.m. and 7 a.m. on Friday, Saturday, and Sunday, Lincoln Way transit will be closed at the Lincoln and the 19th Avenue intersection. All Lincoln Way traffic will be detoured through Irving Street.

Organizing the work in three weekend closures will reduce impact on the public from 40 to 10 days.

The second phase of this project repaves all northbound and southbound lanes of 19th Avenue (also known as State Route 1) between Lincoln Way and Holloway Avenue, approximately 18.8 lane miles, and the Park Presidio Boulevard and the California Street intersection.

The schedule for the final two weekends is:

• 74-hour closure: Friday, May 8 from 3 a.m. until Monday, May 11 at 5 a.m. on Southbound 19th Avenue from Lincoln Way to Sloat Boulevard
• 75-hour closure: Friday, May 22 from 7 a.m. until Monday, May 25 at 10 a.m. on Southbound/Northbound 19th Avenue from Sloat Boulevard to Holloway Avenue

The California Street/Park Presidio intersection will be repaved later during the summer. The schedule also includes upgrading the traffic detection system.

Parking on 19th Avenue will be restricted to work zones during weekend closures; parking is permitted on side streets.

Even though one lane will always remain open to traffic while repaving is underway, motorists are encouraged to use alternative routes.
