The Farallones Avenue Overcrossing
Project Overview
The Farallones Avenue 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.

Reducing greenhouse gases is a goal of the state of California. One of the easiest ways to help meet this goal is to encourage its residents to leave their cars at home and use alternative forms of transportation. Whether it’s commuting to work or simply going to the local store or park, Californians need an attractive, and functional, alternative to using their cars.
The Aesthetic Approach – Blending Functionality And The Area’s Natural Beauty
Overall, the aesthetic concepts draw from the unique, natural features of the Ingleside and Excelsior communities. In addition, Interstate 280 roughly follows the historic path of Upper Islais Creek.
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.
