37 Corbett Route Change & 40-ft. Buses: Effective Wednesday, June 17, 2026

Service Summary & Impacts

A non-safety maintenance issue is affecting the availability of 30-foot hybrid electric Muni buses that run on our hilly community routes. This issue primarily affects our ability to deliver regular service on the 37 Corbett. We apologize for this inconvenience. The SFMTA’s Fleet Maintenance team is working on immediate, short- and long-term solutions.

Currently, the 37 Corbett will have service provided by 40-foot buses until further notice. The longer buses are unable to safely navigate some of the most narrow and winding streets on the route including Buena Vista Avenue, Buena Vista Terrace, and Upper Terrace. The 37 Corbett Route will continue to serve the area using Roosevelt Way in both directions. We also will be adding a temporary inbound stop on Roosevelt Way at Park Hill Avenue. This stop serves riders who usually alight on one of the eliminated segments.

We expect this temporary reroute to be in place for the next few weeks until a short-term solution that avoids service impacts can be put in place. Until then, we will continue to monitor service and make adjustments to the temporary reroute as needed. We expect to have a long-term solution in the next 12 – 18 months.

For some seniors and people with disabilities, walking farther to the nearest stop or paying for other transportation simply isn’t possible. For these riders, the Essential Trip Card provides two to three round trips by taxi and at 20% of the cost of a regular cab fare. The Essential Trip Card is accepted by all taxis in San Francisco.
