27 Bryant Transit Reliability Project

Project Introduction

The 27 Bryant returns to service on January 23, 2021 as a temporarily modified route with travel on 7th and 8th Streets. This modified route uses temporary emergency transit lanes to improve service reliability and build on the foundation of the 27 Bryant Transit Reliability Project. We plan to observe and monitor the performance of this route and engage with community members on their experiences on the modified 27 Bryant prior to making the project’s Phase II improvements.

The 27 Bryant Project focuses improvements on the route north of Market Street in the Tenderloin and Nob Hill neighborhoods where the bus experiences the most delay and slowest travel times. The project aims to make the 27 Bryant more reliable and improve traffic safety for people walking along the route between Market Street and Jackson at Van Ness. By focusing on the slowest segment, we can improve reliability for the entire route, better serving customers in SoMa and the Mission neighborhoods as well. 

On April 16, 2019, the SFMTA Board of Directors unanimously approved the 27 Bryant Transit Reliability Project.

Phase I

In August 2019, the SFMTA started the initial phase of the 27 Bryant Project to deliver transit reliability and safety benefits in advance of the full project construction. A route update and bus stop removals went into effect on August 10, 2019. Due to the COVID-19 pandemic, the scope of the project was adjusted in January 2021 to include a temporary modified reroute via 7th and 8th streets. Through spring 2021, customer feedback on this modified route will directly shape the 27 Bryant route that is made permanent, and may impact the final block-by-block project improvements. Learn more about the initial phase of improvements:

Phase II

In 2020, SFMTA and San Francisco Public Works developed detailed designs for sidewalk extensions at bus stops (transit bulbs) and at intersection corners (pedestrian bulbs). Construction of the full project is scheduled to start in late 2021.

    Transit and Safety Needs

    The 27 Bryant is a route that residents depend on to commute to work and connect to other transit lines. It is also a neighborhood route that many use to reach grocery stores, hospitals, affordable housing, senior centers and more.

    A key bus connection that serves people from a variety of backgrounds, the 27 Bryant was identified as a priority route in the Muni Service Equity Strategy to address neighborhood transit needs.

    Currently the bus gets delayed on the crowded streets of the Tenderloin and Nob Hill. As one of Muni’s ten slowest routes, improving the reliability of the 27 Bryant bus is critical to better serving the community. Keeping the 27 Bryant on schedule is a top priority for riders.

    Additionally three-quarters of the streets on the 27 Bryant’s route through the Tenderloin and Nob Hill are high-injury corridors that have the most severe and fatal traffic injuries in San Francisco. Many of these injury collisions involve people walking in the neighborhood. This needs to change. Improvements to the 27 Bryant route for people walking are critical to achieving the city's Vision Zero goal to eliminate all traffic deaths by 2024.
