9 San Bruno Rapid Project

We're celebrating 10 years of Muni Forward! Pick up a limited-edition Muni Forward Passport at a Transit Month event or participating business while supplies last during the month of September 2024. Use the passport to explore ten of Muni Forward’s project corridors, including the 9 San Bruno.

Project Introduction

Running from Visitacion Valley on the city’s southern edge, all the way to the Financial District, the 9 San Bruno serves many of San Francisco’s working-class neighborhoods, including the Portola District and the Mission. It connects people to essential health services at San Francisco General Hospital and ferries riders from one of the most economically isolated regions of San Francisco into the city’s commercial core.

Since launching the 9 San Bruno Rapid Project in 2009, the SFMTA has added dedicated red transit lanes, numerous safety features for people walking and protected bikeways along the route. These upgrades have boosted efficiency, increased accessibility and improved safety for Muni riders, as well as people walking and bicycling.

Project Status
  1. Completed

Construction on the 9 San Bruno Rapid Project was completed in March 2017, and the results have been very encouraging. Weekend ridership on the route now exceeds pre-pandemic levels, rush hour travel times have dropped by an average of one minute along Potrero Avenue – an important thoroughfare that connects locals to San Francisco General Hospital – and the slowest trips on the route are now about five minutes faster than before the project began.

Some of the most noteworthy improvements made to the 9 San Bruno during the Muni Forward project include:

  • Route efficiency was boosted by adding 3.6 miles of new or upgraded transit lanes, including 2.4 miles of red transit lanes
  • Enhanced safety for people walking and rider accessibility with construction of four new transit islands, 11 transit bulbs, 18 pedestrian bulbs and six new bus stops along the route. For more information on these pedestrian safety features, check out our Pedestrian Improvements Toolkit
  • Travel times have been greatly improved along key corridors – including Potrero Avenue from 18th Street to 24th Street, and along Market Street. As of 2024, the slowest trips are now 5 minutes faster. To make this improvement, the SFMTA removed some 9 San Bruno stops and relocated others. In total, 17 bus stops were consolidated along the 9 San Bruno route
  • Green protected bike lanes have made cycling safer on Potrero Avenue. For more information on protected bike lanes, visit our Bike Facilities Toolkit webpage
