Caltrans Bay Area (District 4) is updating the 2018 Bike Plan! The new Bike Plan will identify barriers to cycling, prioritize improvements and act as a resource for Caltrans staff to implement bike infrastructure on and across Caltrans facilities in the 9-county Bay Area.  

What is a Bike Plan?

The Caltrans Bay Area Bike Plan will identify infrastructure improvements that can enhance bicycle safety, mobility, social equity and preservation throughout the Bay Area and remove some of the barriers to bicycling in the region. The Bike Plan will be developed in cooperation with local and regional partners to ensure that the improvements on the State Highway System complement proposals for local networks.

Vision and Goals 

By 2040, people in California of all ages, abilities, and incomes can safely, conveniently, and comfortably bike for their everyday transportation needs

Image outlining the four goals of the bike plan. Safety: Reduce the number, rate, and severity of bicycle involved collisions. Mobility: Increase bicycling in California. Preservation: Maintain a high quality active transportation system. Social Equity: Invest resources in communities that are most dependent on active transportation and transit.
