Potrero Yard Modernization Project
In 2017, the SFMTA launched the Building Progress Program, $1.2 billion multi-year effort, to repair, renovate, and modernize the San Francisco Municipal Transportation Agency's (SFMTA) aging facilities to keep the City moving.
Potrero Yard, located at Bryant and Mariposa streets, is the first site scheduled under the Program that the SFMTA will modernize and renovate.
The Potrero Yard Modernization Project will replace the obsolete two-story maintenance building and bus yard with a modern, three-story, efficient bus maintenance and storage garage, equipped to serve the SFMTA’s growing fleet as it transitions to battery electric vehicles.
A modern Potrero Yard will better serve our customers by facilitating more reliable and convenient bus service, and by making service more resilient in the event of a natural disaster.
Public tours of Potrero Yard are usually offered monthly. Check here for our current schedule of tours:
