3rd Street Transit and Safety Project

Five of Muni’s busiest bus lines run on 3rd Street in the South of Market neighborhood, including the 45 Union/Stockton, 30 Stockton, 8 Bayshore, and the 8AX and 8BX Bayshore Express buses. But during rush hour, cars block the transit lane and delay thousands of Muni passengers. 3rd Street in SoMa also has some of the most serious traffic injuries in the city. 

The aims of the 3rd Street Transit and Safety Project are to reduce bus delays and improve safety for people walking on 3rd Street between Townsend and Market Streets, as well as to reconfigure traffic lanes to better accommodate existing travel demand patterns. Learn more about the project's proposed improvements: 

Three ways to comment on the proposed changes:

  • Attend the SFMTA Public Hearing on February 19, 2019 at 1:00 p.m., ​​​​​​Room 400 City Hall, San Francisco. (Note that the actual time the item will be heard may be considerably later than 1:00 p.m.)
  • Email comment to: MTABoard@SFMTA.com with subject line “3rd Street Transit and Safety Project”. (Submit comments before the hearing.)
  • Mail comment to: Board of Directors, One South Van Ness Avenue, 7th Floor, San Francisco, CA 94103-5417. (Submit comments before the hearing.)

The SFMTA Board of Directors will make the final approval at the hearing. All comments will be heard by project staff and the SFMTA Board of Directors and will be entered into the public record. 

Sample Intersection Improvements 

The sample intersection illustrated below shows proposed improvements to 3rd Street for transit and people walking. By shifting the transit lane away from the curb, the project can reduce bus delays and provide an additional right-turn lane to accommodate Bay Bridge traffic. Pedestrian improvements will improve safety for people walking. In order to accommodate these improvements, one through lane of traffic would be removed outside of rush hour, and some curbside parking would be converted to a traffic lane during rush hour. Some curbside parking would be removed to accommodate right turn lanes.Plan drawing of a sample 3rd Street intersection showing proposed orientation of transit lane in relation to other traffic lanes on 3rd Street. Below drawing lists proposed improvements including 1) Relocated transit lane reducing conflicts with cars, 2) Corner sidewalk extensions for shorter crossings, 3) High-visibility crosswalks, 4) Upgraded wheelchair ramps, 5) Advance limit lines to stop cars before crosswalk, 6) Head starts for people walking in crosswalk, 7) Wider sidewalks at bus stops, 8) Right turn-only signals reducing conflicts with pedestrians.

Graphic of Proposed bus stop updates on 3rd street, south of market. Updating bus stops to be more evently-spaced (on every other block) allows for better transit access and reduced delays. See below for proposed stop changes. Current 3rd street bus stops that are proposed to continue include those at Townsend, Folsom, Mission and Market. The stop at Howard Street is proposed to be eliminated and the stop at Harrison Street is proposed to be moved to Bryant Street.

Transit and Safety Needs

Bus Delays

During the busiest hours, 3rd Street is used by close to 40 Muni buses carrying thousands of passengers – one bus every 90 seconds. Cars and trucks head downtown and to the Bay Bridge and Highway 101, While 3rd Street does have a lane prioritized for transit, during rush hour it is blocked by vehicles waiting to turn right, delaying thousands of Muni passengers.

High-Injury Corridor

Crowds of people walk to the area’s many businesses, cultural and civic destinations. As a one way street with up to six lanes, 3rd Street is one of the city’s high-injury corridors that have the most severe and fatal traffic injuries in San Francisco. Many of these injury collisions involve people walking in the neighborhood, which features several low-income senior housing projects, Bessie Carmichael Middle School and multiple major cultural and civic facilities (including Moscone Center and the San Francisco Museum of Modern Art).

Improvements to 3rd Street for people walking are also critical to achieving the city's Vision Zero goal to eliminate all traffic deaths by 2024.

Thank you for your feedback

The 3rd Street Transit and Safety Project proposal was developed with input from over 200 Muni passengers, pedestrians and motorists on 3rd Street. Feedback was received from local merchants, senior communities, neighbors, community organizations and institutional stakeholders. Take a look at highlights of the community's feedback. Feedback surveys were offered in English, Chinese, Spanish and Filipino. The feedback surveys are now closed.
