Balboa Park Station Area Circulation Study | Home

I-280 and ramp at Balboa Park Station


The Balboa Park BART/Muni Station is one of the busiest intermodal transit facilities in the region. As the major hub for the southern part of San Francisco, the station serves more than 24,000 passengers daily with its four BART lines, multiple major local bus routes, and three light rail transit (LRT) lines. But access to the station, particularly for non-auto modes, is complicated by tightly squeezed station functions and its location adjacent to the I-280 Geneva-Ocean Avenue interchange system, whose multiple on- and off-ramps deliver heavy auto traffic to the station and its surrounding neighborhoods, causing multimodal conflicts with transit and pedestrians.

This Circulation Study focuses on potential modifications to the Balboa Park Station and adjacent I-280 interchanges at Geneva Avenue and Ocean Avenue. The main goals of the Study are to:

  • Reduce multimodal conflicts (vehicles, transit, pedestrians) at the I-280 freeway ramps while not substantially degrading vehicle operations in the area, including the I-280 freeway mainline.
  • Provide safe, accessible, and convenient connections for pedestrians, bicycle, and intermodal travelers.
  • Develop cost-effective solutions that support the community values and goals, without substantial construction-related impacts, that can be implemented in 2–10 years.


Balboa Park Station Area Study community meetingA Balboa Park Community Advisory Committee (BPCAC), whose membership and bi-monthly meetings are open to the public, monitors progress and provides input on the multiple station-related improvements currently under development. The BPCAC also provides input on this Study’s work to develop the next generation of capital improvements in the station area. The San Francisco County Transportation Authority (SFCTA) is also conducting additional outreach, including public meetings, to seek wider input throughout the study.

On January 30, 2014 the BPCAC and SFCTA held a joint community meeting for the Study. The meeting was lively and well-attended. The SFCTA presented the Study alternatives and findings; meeting attendees were given the opportunity to ask questions and provide feedback during an open forum and also via comment cards.

On September 30, 2013 the SFCTA hosted the first of two community meetings for the Study. Meeting attendees were briefed on the existing conditions assessment and then invited to participate in working group discussions of the three conceptual alternatives developed in the initial study phase. In addition to providing feedback during the working groups, participants completed comment cards. See the Outreach 1 Meeting Summary.

  • Preliminary Alternatives Development and Evaluation (Spring-Summer 2013)
  • Full Concept Evaluation, including Cost Estimates (Fall 2013)
  • Final Report / Recommendations, including Implementation Plan (Winter 2014)


Previous plans in the study area, including the Planning Department’s 2009 Balboa Park Station Area Plan and the San Francisco Municipal Transportation Agency’s recently completed Balboa Park Station Capacity Study,  recommended multiple improvement concepts. Of those recommendations, several short-term projects have been completed or are underway. But the mid- and long-term visions remain to be clarified. This study’s focus is on a particular mid-term concept that the Station Capacity Study did not examine in detail: potential modifications to the I-280 interchange and accompanying station reconfiguration. The study will also coordinate with other efforts, such as the Geneva Avenue Transit Preferential Streets study that explored transit operational improvements whose implementation could have synergies with I-280 ramp changes.


The SFCTA is leading this study in collaboration with:

  • California Department of Transportation (funder)
  • San Francisco Municipal Transportation Agency
  • Bay Area Rapid Transit District
