16th Street Improvement Project, Phase 1 and Phase 2

Project Introduction

The 16th Street Improvement Project will improve transit reliability and travel time by nearly 25%, while addressing safety and accessibility for all users of the corridor. It will address the transportation needs of current and future residents, workers and visitors to the southeastern portion of the 22 Fillmore route along 2.3 miles of 16th Street, including transit-only lanes, transit bulbs, new traffic and pedestrian signals, as well as new streetscape amenities. To better leverage public funds and minimize construction impacts, the project will also include replacing old underground water (only Phase 1) and sewer lines. Once finished, the street will be entirely repaved.

To allow for zero-emission transit service into Mission Bay, the project will also include extending the overhead contact system (OCS) that powers trolley buses on 16th Street from Kansas Street to Third Street. Additionally, new bike lanes have been added to 17th Street to create a continuous route from Mission Bay to the Mission Neighborhood.

Project Objectives:

  • Improve reliability and travel time of the 22 Fillmore for the 18,000 daily riders by nearly 25% in the project area
  • Improve safety on 16th Street for people walking, bicycling, and driving
  • Improve bike route from Mission to Mission Bay 
  • Upgrade aging sewer infrastructure, and water infrastructure for Phase 1 east of Potrero Avenue 
  • Facilitate zero-emission transit service to connect the Mission Bay neighborhood to the Mission

This project is part of Muni Forward, an ongoing initiative to create a safe, reliable and comfortable experience on and off transit.


As part of the Transportation Effectiveness Program (TEP), now called Muni Forward, the "22 Fillmore Transit Priority Project" (now called the "16th Street Improvement Project") is part of a larger network of proposed or planned improvements to the Muni system in order to improve reliability and speed, and increase overall system effectiveness. The TEP took a system-wide approach in its assessment with an understanding that for transit to work well throughout the city, key heavy-use routes like the 22 Fillmore needed to serve riders and the overall system more efficiently.

Originally the 16th Street Improvement Project was proposed as one large, multi-year, multi-mile project that would span the entire 2.3 mile corridor from Church Street to 3rd Street, but ultimately the project was split into two phases, with Phase 1 from Potrero Avenue to 3rd Street starting construcution first, then Phase 2 from Church Street to Potrero Avenue. Contractually each phase is treated as a completely separate project with its own bidding process, contractor, and construction timeline.


Outreach for both phases began in 2015 to get feedback from the community on the then proposed changes to the street and to the 22 Fillmore. Community meetings about the project proposal began in 2015, with some 22 Fillmore-related meetings taking place in 2014. In addition to community meetings, the community was engaged through mailers to residents and business owners along the corridor, ads in local newspapers, blog posts, bus shelter posters, and targeted emails to stakeholders. 

SFMTA public hearing was held in October 2015 and the SFMTA Board approved the project in January 2016.

Construction Timeline

Phase 1

Phase 1 construction will be implemented on16th Street from Potrero Avenue to 3rd Street with work moving west to east. Construction is ongoing and is scheduled to be complete in spring 2020. 

Phase 2

Phase 2 construction will be implemented along 16th Street between Church Street and Potrero Avenue. Construction is scheduled to begin spring 2020. 

Along with the important improvements to 16th Street, the eastern end of the 22 Fillmore route will shift to serve the growth in jobs, housing and hospitals in Mission Bay. A replacement route, 55 Dogpatch, was created through a community process that will ensure service is maintained to Potrero Hill and the Dogpatch areas once the 22 Fillmore shifts to Mission Bay and 3rd Street.
