SFMTA closes Kearny Street for bridge demolition in August | The Locally Times
Full weekend closures of Kearny Street between Clay and Washington streets will shutter the Portsmouth Square Garage and reroute three Muni bus lines.
The San Francisco Municipal Transportation Agency (SFMTA) scheduled two full weekend closures of Kearny Street between Clay and Washington streets for the demolition of the Kearny Street pedestrian bridge. The closures run from 1:00 a.m. Saturday, August 1, to 5:00 a.m. Monday, August 3, and from 1:00 a.m. Saturday, August 8, to 5:00 a.m. Monday, August 10. ## Parking and Access The Portsmouth Square Garage will remain inaccessible to the public during the two 52-hour weekend closure windows. The SFMTA directs motorists to the St. Mary’s Garage at 433 Kearny Street. The city will maintain local access for businesses on the east side of Kearny Street between Clay and Merchant streets, but all other through-traffic must follow posted detours. ## Traffic Detours Partial lane closures are scheduled for July 30–31 and August 3–7, during which the SFMTA plans to keep at least two lanes open. For the full weekend closures, the agency published two primary detour routes. Northbound traffic will divert west on Sacramento Street, north on Stockton Street, and east on Jackson Street to return to Kearny Street. Alternatively, traffic may travel east on Clay Street, north on Sansome Street, and west on Washington Street to reach Kearny Street. ## Transit and Regional Impacts The 8 Bayshore, 8AX Bayshore A Express, and 8BX Bayshore B Express bus routes will reroute during the two full weekend closures. The SFMTA has not released turn-by-turn routing details or projected travel time increases for these lines. Additionally, the Broadway Tunnel is scheduled for closures from July 2026 through the fall of 2027. The project documentation does not specify how these concurrent closures will affect traffic congestion in the Chinatown corridor. ## Key Questions **Will I be able to park in the Portsmouth Square Garage during the construction?** The garage will be closed during the two full weekend periods: August 1–3 and August 8–10. The SFMTA recommends using the St. Mary’s Garage at 433 Kearny Street. **How will the 8 Bayshore bus route be affected?** The 8 Bayshore, 8AX, and 8BX bus routes will be rerouted during the two full weekend closures.
