San Francisco State Route 1 Paving Project

Caltrans Repaving Two Sections of State Route 1 in San Francisco

Caltrans is currently repaving the southern portion of State Route 1 (SR-1) in San Francisco.  The mile-long project, between Alemany Boulevard and Holloway Ave, began late March 2020 and is expected to complete in late April 2020.  Roadwork has been taking place seven-day-a-week from 9:00 AM to 9:00 PM.  Crews are still intermittently closing two lanes in both directions for restriping. The Brotherhood Way ramps will also have intermittent closures as well, but marked detours will be in place. 

Additionally, crews have just started grinding and paving the approximate two-mile long northern potion of SR-1 between the southern entrance of Golden Gate Park at Lincoln Way up to Lake Street by the entrance into the General Douglas MacArthur Tunnel.  Crews will be working from 9:00 AM to 9:00 PM seven-days-a-week in two lanes of the three-lane roadway through mid to late May 2020.  They will start in the southbound (SB) direction first then switch to the northbound (NB) side, however, one lane of traffic will remain open at all times.  Motorists should expect delays and drive with caution through the construction zone. The work will repair multiple potholes and cracks due to constant wear and tear.  Once completed, residents and motorists will benefit from a safer, smoother drive.

These projects are a continuation of a $13 million one-year-long project.  Last spring and summer, Caltrans replaced the median barrier in Golden Gate Park between the 25th Avenue split at Crossover Drive out to Fulton Street.  The new barrier is now taller, blocking glare from oncoming headlights and stronger, replacing an old barrier that was worn by weather and traffic collisions.  In addition, Caltrans repaired, replaced, and upgraded various drainage pipes and curb ramps along SR-1 to comply with the Americans with Disabilities Act (ADA).
