The Central Avenue / Interstate 80 (I-80) underpass in Richmond leads to a lot of great places—the San Francisco Bay Trail, Point Isabel Dog Park and the El Cerrito Plaza BART station, to name a few. We want your ideas on how to transform the underpass into a high-quality pedestrian and bicycle connection!
Join us a Community Workshop to share ideas on the project design.

In conjunction with the District 4 Bicycle Plan, A Guide to Bikeway Classification was developed to clarify the types of bicycle facilities. It also includes examples of techniques that can improve the safety and operations of bicyclists at intersections. Click the cover image below to view the guide.
The Caltrans District 4 Bike Map covers the State highway system within the nine Bay Area counties, showing which State highways are open to bicyclists, where they are prohibited, and an alternate route available where bicycling is prohibited. This map is for informational purposes only and should not be used for bicycling directions.
The Caltrans District 4 Pedestrian and Bicycle Program performs design review on various projects within the State Highway System affecting pedestrians and bicyclists and coordinates District 4 Pedestrian and Bicycle Advisory Committee activities.
