Project Introduction

Before the pandemic, the J Church served 17,000 Muni riders each weekday in Noe Valley, the Castro, the Mission, Glen Park and Mission Terrace, and riders continue to return. We’ve heard concerns about Muni service reliability along the J Church corridor including long transit wait times, as well as concerns about vehicle speeding and safety for people walking. As part of the Muni Forward program, multiple J Church projects will focus on making improvements to address these concerns along Church Street and San Jose Avenue. 

Reliability challenges 

When delayed, the J Church often sees long gaps in service followed by the bunching of two or more trains in a row. A 2013 project improved reliability for the J Church on Church Street between Duboce and 16th Street. The project added red transit lanes and left-turn restrictions. The project was able to reduce travel time variability by 27%. It also improved travel times up to 14% on that segment. The SFMTA is building on the success of this project to address delays on the remainder of the line. 

Over the last few years, we have heard the following concerns from J Church customers: 

  • Concerns about transit reliability and travel times 
  • Requests to improve safety, accessibility and features at train stops 
  • Requests to improve safety for people walking along and near the J Church 

No changes to the J Church route or frequency were being considered as part of this project.
