    23rd Avenue Slow Street Evaluation 

    Following the SFMTA Board’s approval of 23rd Avenue, the SFMTA Project team collected additional data analysis to assess how the street is performing against the Slow Streets Program targets: 

    • Vehicle speeds at or below 15 mph 
    • Vehicle volumes less than 1,000 per day 

    23rd Avenue meets both the Program vehicle speed and volume targets.

    For additional information on how this street compares to others in the Slow Streets program, or for overall program findings, please see the 2023 Evaluation Report.
