Major Paving Project on 19th Avenue in San Francisco Prompts Traffic Warnings for Commuters and Businesses

April 26, 2026 - 20:54

Drivers in San Francisco are being urged to plan for significant delays as Caltrans undertakes a major repaving project on a critical stretch of northbound 19th Avenue. The busy corridor, which serves as a primary artery for commuters traveling through the western side of the city, is now closed to traffic between Sloat Boulevard and Lincoln Way. The closure, which began over the weekend, is expected to cause ripple effects throughout the neighborhood as crews work to resurface the roadway.

Local business owners are bracing for the impact of reduced customer access during the construction period. Many shops and restaurants along the affected stretch rely heavily on drive-by traffic and easy parking, both of which will be severely limited during the closure. Some merchants have expressed concern that the extended delays could deter regular patrons and hurt sales, especially during what is typically a busy time of year.

Caltrans officials have stated that the repaving is necessary to address deteriorating pavement conditions and improve safety for drivers, cyclists, and pedestrians. The project is part of a broader effort to maintain the city’s aging infrastructure. While the agency has not provided an exact timeline for completion, crews are working around the clock to minimize the disruption. Motorists are advised to seek alternate routes, such as Sunset Boulevard or Highway 1, and to allow extra travel time. Public transit options, including Muni bus lines that run parallel to the construction zone, may also experience delays as traffic is rerouted.
