December 2023 Proposed Changes to Minnesota Slow Street

Following the SFMTA Board’s approval of Minnesota Street as a permanent Slow Street in December 2022, the SFMTA Project team conducted additional data analysis to assess how the street is performing against the Slow Streets Program targets of vehicle speeds at or below 15 miles per hour and vehicle volumes less than 1,000 per day.

Minnesota Street did meet the program speed target but not the volume target. The Slow Streets team is therefore proposing the following tools to reduce vehicle volumes:

  • A diverter island restricting northbound vehicle traffic at Minnesota Street &19th Street to reduce cut-through car traffic.
  • A painted safety zone and median island at the southwest corner of Minnesota Street and 18th Street to slow right turns from eastbound 18th Street while preserving southbound access to the loading zones and the UCSF police vehicle yard on Minnesota Street.
  • Painted safety zones (PSZs) on Minnesota Street at 18th Street and 19th Street, which can serve as community spaces for possible street murals and other community art.
  • A new traffic calming island located midblock between 20th and 22nd streets to slow speeds at the southern block of the corridor, which requires lengthening nearby red zones for access to fire hydrants.
  • Slow Streets pavement markings, identification and wayfinding signs, and advisory 15 mph signs to provide additional visual cues to all users that the corridor is a Slow Street.
