SF Muni Upgrades 21 Routes — Better Transit Ahead
San Francisco Muni modifies 21 routes through Wednesday due to construction projects
Muni Alters Service on 21 Routes This Week
San Francisco's Muni system is running modified service on 21 routes through Wednesday, affecting riders across the city. The San Francisco Municipal Transportation Agency announced the changes January 10, impacting six rail lines and 15 bus routes. Construction projects and special events are driving most disruptions, though officials didn't specify how many riders will be affected.
Construction Projects Drive Most Changes
The Twin Peaks Tunnel Track Renewal Project continues to affect multiple Muni Metro lines, requiring bus substitutions on several routes. Work on the Muni Metro East Maintenance Facility is also causing service modifications, particularly on the T Third line. Various street improvement projects throughout the city are forcing bus route detours. Transit officials said the construction work is part of ongoing infrastructure upgrades, though specific completion timelines for individual projects weren't provided in the advisory.
Six Rail Lines See Major Service Changes
The J Church, K Ingleside, L Taraval, M Ocean View, N Judah, and T Third lines are all operating with modified service during the advisory period. Bus shuttles are replacing rail service on affected segments, with specific substitution patterns varying by line and time of day. The 15 affected bus routes include the 5 Fulton, 8 Bayshore, 14 Mission, 22 Fillmore, 28 19th Avenue, 29 Sunset, 30 Stockton, 38 Geary, 43 Masonic, 44 O'Shaughnessy, 48 Quintara/24th Street, 49 Van Ness/Mission, 52 Excelsior, 54 Felton, and 91 Owl. Officials outlined general service modifications but didn't provide detailed frequency information for replacement buses.
Special Events Add Weekend Complications
A San Francisco 49ers home game Saturday at Levi's Stadium and a Golden State Warriors game Sunday at Chase Center will create additional transit demand and traffic impacts. The SFMTA typically adds extra service for major sporting events, though specific service increases weren't detailed in this week's advisory. The changes remain in effect through Wednesday, January 14, with normal service patterns expected to resume after the advisory period ends.
Riders Should Plan Extra Travel Time
Commuters using affected routes should expect longer travel times and consider alternative routes where possible. The agency said it'll provide updates if conditions change, though a timeline for when additional details will be available wasn't specified. Moovit provides real-time updates for all Muni routes, helping riders navigate service changes and find the fastest available connections during construction and special events.
