Map of re-routes and service changes

The San Francisco Municipal Transportation Agency (SFMTA), which manages transportation in the city, including the Municipal Railway (Muni), today reminds Muni customers that as of Saturday, Jan. 21 the 30 Stockton and 45 Union-Stockton Muni routes will be rerouted from Stockton and 4th streets to Mason and 5th streets for the duration of Central Subway construction around Union Square, approximately four years. A temporary 8 Shuttle route will be in place between Broadway and Kearny Street and SoMa to ensure sufficient downtown capacity on the 8X Bayshore bus routes.

The 30 and 45 routes use trolley buses that require an overhead catenary wire system to power the vehicles. As construction advances for the Central Subway Union Square utility relocation and station construction, these routes must be modified to accommodate the increased construction activity along Stockton Street. More flexible motor buses are used for the 8X routes and will be used for the 8 Shuttle that will continue to operate down Stockton Street during peak service hours until later in the construction schedule.

Central Subway Transit Impacts

30 Stockton and 45 Union-Stockton Reroute

  • Southbound buses travelling to 3rd and Townsend streets will be rerouted onto Sutter Street, then south on Mason Street, east on Market Street and south on 5th Street.
  • Northbound buses will remain on their regular route.

8 Shuttle Service

  • The 8 Shuttle will operate daily from 9:30 a.m. to 6:30 p.m.
  • The shuttle route will begin at Kearny and Pacific then left on Broadway, left onto Stockton Street, cross Market Street onto 4th Street, turn left onto Folsom Street and left on 3rd Street.
  • The terminal for the Chinatown Shuttle will be at Kearny and Pacific.

Upcoming Reroute

  • On Jan. 21 the 8X/8AX/8BX Bayshore buses will maintain their current routes; however, they will be rerouted at a later date to accommodate additional construction activity.
  • Once the 8X routes are diverted off of Stockton and 4th streets due to construction, the 8 Shuttle will be eliminated.

Union Square Traffic Impacts

Union Square utility relocation construction continues after resuming on Jan. 3 and includes the following traffic impacts:

  • At all times only one lane of traffic will be available on Stockton Street between Sutter and Market streets.
  • The open lane of traffic on Stockton Street will be available for taxis, tour buses and delivery trucks only.
  • All private automobiles going to 4th Street and other SoMa destinations will be required using traffic detours.
  • Garages within the construction zone are open and accessible using traffic detours.
  • Noise and dust can be expected as a result of the construction activity.
  • The contractor will always maintain a safe pedestrian path of travel and pedestrian access to all stores during business hours.
