Plan Bay Area supports the vitality of existing communities by focusing the lion’s share of investments on maintaining and boosting the efficiency of the existing transit and road system. These transportation investments act as magnets for job growth and new homes in these areas.

The Plan Bay Area interactive project map is a tool that allows you to see and explore the Bay Area’s 100 largest transportation projects (in terms of cost) in a simple and easy-to-use format. Whereas regional planning focuses on the overall health of the entire region, this interactive map site is all about allowing users to zoom in on individual transportation projects. In other words, this map is designed to help visualize the major transportation investments outlined in the currently adopted Plan Bay Area, approved by MTC and ABAG in July 2013.

The interactive project map displays information by project category—road pricing, highway, and transit—and allows users to choose whether to view these projects on top of street-level, region-centric or satellite maps. A general project description, along with more in-depth information about the project’s location, sponsor, expected completion date and cost, is provided. A photo and rendering gallery also is included for many projects.

We hope you enjoy your exploration of this map and data and find it useful in identifying the investments the Bay Area is making in its regional transportation network.
