The Transportation Authority’s I-280 Ocean Avenue Off-Ramp Project study team has advanced designs for the project, a community priority that was recommended in the Transportation Authority’s prior 2014 Balboa Park Circulation Study. The project is located adjacent to the Balboa Park BART/Muni Station, Lick Wilmerding High School, and City College of San Francisco’s Ocean Campus, a busy area for drivers, pedestrians, transit users, and bikers.
The study team is conducting outreach to share the latest design for the off-ramp, which is located on San Francisco’s Vision Zero High-Injury Network. The project’s design aims to improve safety for all travelers, particularly to reduce conflicts between motor vehicles and pedestrians and bicyclists, while maintaining multi-modal circulation.
The proposed southbound off-ramp design converts the existing free-flow right turn (westbound vehicle movement) to a signal-controlled exit onto Ocean Avenue, paired with pedestrian and bike improvements from the I-280 overpass to Howth Street. This design is consistent with prior planning efforts, including the Transportation Authority’s Ocean Avenue Mobility Action Plan Study.
The proposed freeway ramp design would include:
- New traffic signal at Ocean Avenue
- Dual lanes on the off-ramp to accommodate vehicle queues during red signal phases;
- Improved crosswalk and curb ramps across ramp intersection with Ocean Avenue;
- Making existing bicycle lane on Ocean Avenue across the freeway green;
- Continuing green bicycle lane with protected bike lane treatment west of the off-ramp to Howth Street; and
- Wider sidewalk on Ocean Avenue west of ramp to Howth Street (consistent with Ocean Avenue Mobility Action Plan Study recommended concept).
Outreach is currently underway with community meetings with neighborhood groups, businesses, and institutions. A project update will be presented to the Transportation Authority Board at the June 24 meeting. To request a presentation, contact the project team at aliza.paz@sfcta.org.
The Transportation Authority is collaborating with Caltrans and city agencies to complete project designs, utilizing funding from the California Transportation Commission’s Senate Bill 1 Local Partnership Program funds and the Transportation Authority’s transportation sales tax local matching funds.
The study team anticipates presenting project design and outreach results, cost and funding updates, as well as potential next steps to the Transportation Authority Board this fall.
