Lyon Slow Street
Project Introduction

Lyon Street from Turk Street to Haight Street in the North of the Panhandle and Haight-Ashbury neighborhoods was approved as a Slow Street by the San Francisco Municipal Transportation Agency (SFMTA) Board on December 6, 2022. This corridor had initially been implemented as a COVID-19 Response Slow Street .

Lyon Slow Street Evaluation

Following the SFMTA Board’s approval of Lyon Street, 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 

Lyon Street meets the program vehicle volume target, but does not meet the vehicle speed target.

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.

Next  Steps

Lyon Street did not meet program speed targets but did meet program volume targets. The Slow Streets program team will:

  • Consider additional traffic calming tools and prepare a design to slow vehicle traffic. The design will be posted on this page and a public hearing will provide an opportunity for feedback.
  • Continue to monitor vehicle volumes on this street.
