SF Half Marathon Reroutes 4 Muni Bus Lines Sunday
San Francisco Muni riders should plan for service changes Sunday as the San Francisco Half Marathon and 5K reroutes four bus lines through Golden Gate Park and the western neighborhoods. Routes 18, 33, 43, and 44 will detour around the race course starting at 7:50 a.m., transit officials said. The event winds through Golden Gate Park, the Panhandle, and along the Great Highway, affecting morning commutes for riders who use these lines regularly.

Race Course Affects Key Park and Beach Routes
The affected routes serve some of San Francisco's most popular recreational areas, connecting neighborhoods to Golden Gate Park and Ocean Beach. Routes 18 and 33 typically run through the park's northern edge, while the 43 and 44 serve the western neighborhoods near the Great Highway. Transit agencies routinely reroute buses around major running events to ensure participant safety while maintaining service to nearby areas. Officials didn't specify exactly which streets the detours will use or how long delays might last.
Morning Service Changes Expected
The reroutes will begin when the race starts at 7:50 a.m. Sunday, February 1, though officials haven't said when normal service will resume. Transit agencies typically restore regular routes once race participants clear the course, which for half marathons usually takes three to four hours. The agency didn't provide details about whether additional buses will be deployed to handle displaced riders or if service frequency will change on the affected routes. Riders should expect longer travel times and possible crowding on nearby routes that aren't affected by the detours.

Service Returns After Race Clears
Normal bus service will resume once runners clear the course, though the transit agency didn't announce a specific time. Officials said they'll monitor the race's progress and restore regular routes as streets reopen. The San Francisco Municipal Transportation Agency typically coordinates with race organizers to minimize disruptions, but specific details about that coordination weren't available.
Riders Should Plan Alternate Routes
Commuters who regularly use routes 18, 33, 43, or 44 on Sunday mornings should allow extra travel time or consider alternate lines. Officials said riders can expect service to return to normal by early afternoon.
