Brannan Street

The goal of the Brannan Street Safety Project is to improve safety and comfort along the corridor for those who walk, bike, and drive in the neighborhood. This project will improve safety on Brannan Street between Division Street and the Embarcadero in the South of Market (SoMa) neighborhood by reducing the number of travel lanes (four lanes to three lanes), installing bike lanes, and improving intersection safety. 

Between July 2011 and June 2016, there were 143 injury collisions, where one was fatal. Brannan Street is on the city’s High-Injury Network, which are the 13 percent of city streets that account for 75 percent of San Francisco’s traffic related injuries and fatalities. The Brannan Street Safety project supports San Francisco’s Vision Zero goal of eliminating all traffic deaths by 2024.

Today, Brannan Street is generally a four-lane undivided roadway, providing a major access point to the I-280 freeway at 6th Street. Converting the street to a three-lane roadway with left-turn pockets will improve traffic flow, while adding bicycle lanes will provide safety enhancement and bicycle connectivity. The proposed project design elements, include: 

  • Bike lanes in both directions to provide dedicated space for people riding bikes
  • Traffic lane reduction to redistribute roadway space to all road users
  • Center two-way left turn lane to allow flexibility for vehicles to turn left at alleys or driveways without blocking a travel lane
  • Better designed intersections to provide left turning vehicles with a separated turning lane and pedestrian safety improvements through more visibility at intersections
  • Traffic signal timing changes that will enhance safety and improve the efficiency of traffic flow


The Brannan Street Safety project is part of a comprehensive upgrade of the Brannan Street corridor. This is a citywide effort that involves improving the sewer line, installing new curb ramps where needed, and installing new fiber optic cable. After this work is completed below ground, the road will be repaved. Once repaved, SFMTA will be able to install the proposed street configuration by reducing a lane of traffic and adding bike lanes, center two-way left turn lane, and other safety improvements.


From October 2017 to August 2018, the Brannan Street Safety Project team has engaged various neighborhood groups including: South Beach | Rincon | Mission Bay Neighborhood Association, South Beach & Mission Bay Business Association, East Cut Central Business District, Eastern Neighborhoods Citizen Advisory Committee, and the Central Waterfront Advisory Group. During this time, the project team also mailed 6,300 postcards to properties near Brannan Street and walked door-to-door meeting with fronting properties to gather feedback on transportation safety concerns and changes to parking and loading.


This project is funded by local Proposition B San Francisco General Fund.
