Central Avenue / Interstate 80 (I-80) Underpass Improvement Project

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 at a Community Workshop to share ideas on the project design.

Please view and share the flyer.

The Caltrans District 4 Bike Plan final report is now available!

The report summarizes the process in developing the Plan, which builds on the 2017 California State Bicycle and Pedestrian Plan, Toward an Active California, evaluates bicycle needs on and across the State Transportation Network in District 4, and prioritizes improvements to develop and support an integrated bicycle network for the Bay Area.

For more info, visit the D4 Bike Plan website.

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.

Classification

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.
