Caltrans District 4 Bike Plan

The Caltrans District 4 Bike Plan (Plan) for the San Francisco Bay Area was developed within the framework of Toward an Active California, the California State Bicycle and Pedestrian Plan. This framework includes an overall vision, goals, objectives, and strategies to improve bicycle safety and mobility throughout the State. The District 4 Bike Plan, the first of its kind in the State, evaluates bicycle needs on and across the Bay Area’s State transportation network and identifies infrastructure improvements to enhance bicycle safety and mobility and remove some of the barriers to bicycling in the region. This Plan will guide District 4 and its partners to develop an integrated bicycle network for the Bay Area.

Many of the improvements identified in the Plan are conceptual and will require further study and coordination with local jurisdictions and stakeholders. The Plan will be updated regularly as future needs and opportunities are identified and evaluated.

The Plan was developed with input from local and regional partners and stakeholders to ensure that proposed improvements are consistent with local efforts and reflect stakeholder needs. A public outreach process included an online mapping survey, focus group meetings, two rounds of community workshops, and an online comment tool. A Technical Advisory Committee made up of representatives from city, county, and regional agencies as well as advocacy and stakeholder organizations helped inform the process.

The Caltrans District 4 Bike Plan final report summarizes the development of the Plan and highlights key findings. Additional information can be found in the Documents tab.

This map is an interactive tool to view the needs analysis and priority improvements identified in the Plan. The needs analysis is based on multiple data sources to rank highway segments on Level of Traffic Stress (LTS), low stress connectivity (permeability), collision history, and potential bicycling demand. Improvements are classified by prioritization categories of: top tier, mid tier, and low tier. More information on the needs analysis and improvement prioritization is available in the Documents section.
