Lane Closures Jam 19th Avenue Traffic

Caltrans started the first of three weekend repaving closures on Highway 1, better known in San Francisco as 19th Avenue, on Friday, April 24. (dot.ca.gov) (nbcbayarea.com) The closure covered the stretch from Sloat Boulevard to Holloway Avenue near San Francisco State University, with two lanes shut and one lane left open. That remaining lane was reserved for public transit, emergency responders and local access. (sfmta.com) (sfusd.edu) Caltrans and San Francisco Municipal Transportation Agency officials told drivers to avoid 19th Avenue and use Sunset Boulevard, Junipero Serra Boulevard and Interstate 280 detours instead. The first closure was scheduled from 7 a.m. Friday, April 24, to 5 a.m. Monday, April 27. (sfmta.com) (localnewsmatters.org) Muni service changed too. San Francisco Unified School District said the northbound closure affected the 28, 28R, 48, 66 and 91 lines, while the 7, 29, N Bus, L Taraval and N Judah could see delays. (sfusd.edu) (sfmta.com) The closures are tied to a broader Caltrans rehabilitation job that will repave northbound and southbound lanes of 19th Avenue between Lincoln Way and Holloway Avenue, plus Park Presidio Boulevard to the California Street intersection. Caltrans says the project is targeted for completion by December 2026. (dot.ca.gov) Public Works has described 19th Avenue as part of a larger combined city project involving roadway work, utility upgrades, traffic-signal changes and transit improvements along the corridor. Earlier city planning documents said most drivers on 19th Avenue are passing through rather than ending their trips in the project area. (sfpublicworks.org 1) (sfpublicworks.org 2) NBC Bay Area reported the repaving weekends run through late May, making this first closure the start of a longer series rather than a one-off traffic jam. For westside commuters, the immediate problem was simple: fewer lanes on one of San Francisco’s main north-south routes. (nbcbayarea.com)
