The Farallones Street Pedestrian Overcrossing Project
Project Overview
The Farallones Street Pedestrian Overcrossing Project will replace the existing pedestrian overcrossing on I-280, where the current structure is too steep and where freeway clearance is deficient at #5 lane SB 280. The new pedestrian overcrossing will be ADA accessible with proper slope and clearance, and beautifully designed. Additional work will include polyester overlay work east of the US-101 interchange by China Basin on the double deck section and beyond. New asphalt concrete pavement will be laid onto all I-280 on and off ramps in San Francisco.
When completed the new overcrossing will feature an ADA compliant grade across the highway while featuring an improved width and lighting that will encourage people to reconsider using automobiles for local commuting.
This website will be continually updated with new images and studies related to the project. We encourage you to visit regularly to view the progress of the project and to learn more about it.

Blending Functionality And The Area’s Natural Beauty
Reducing greenhouse gas emissions is a key priority for the state of California. One of the most effective ways to support this goal is by encouraging residents to leave their cars at home and choose alternative modes of transportation. Whether commuting to work or making a quick trip to the local store or park, Californians need attractive, functional options that make walking or biking easier. The new pedestrian overcrossing will help meet this need and provide a valuable solution for the community.
Colors and textures of the project will seek to reference and unify with vegetation and established objects on both sides of the highway including Muni, BART, and Cayuga Park.

Cayuga Park is also on the migratory path of the Cliff Swallow, a bird that is known for its synchronized flying displays. Concepts for the large retaining wall facing the freeway below San Jose Avenue convey movement in the form of a murmuration of birds in flight, referencing the migratory Cliff Swallows that pass-through Cayuga Park while evoking the large trees that reside in the area.
