MTC and the Association of Bay Area Governments (ABAG) have just released the Final Plan Bay Area 2040. After two years of public discussion and technical work, the Final Plan Bay Area 2040 is an updated long-range Regional Transportation Plan and Sustainable Communities Strategy for the nine-county San Francisco Bay Area.

Proposed Amendment to Plan Bay Area 2040 — Interstate 680 Express Lanes Gap Closure Project (Alameda County)

Plan Bay Area 2040 is the Bay Area’s roadmap for:

  • Forecasting transportation needs through the year 2040
  • Preserving the character of our diverse communities
  • Adapting to the challenges of future population growth

The effort grew out of the California Sustainable Communities and Climate Protection Act of 2008 (California Senate Bill 375, Steinberg), which requires each of the state’s 18 metropolitan areas – including the Bay Area – to reduce greenhouse gas emissions from cars and light trucks. Plan Bay Area 2040 is a limited and focused update of the region’s previous integrated transportation and land use plan, Plan Bay Area, adopted in 2013. View the final Plan Bay Area 2040 at

MTC and ABAG have worked together to craft a plan that will support a growing economy, provide more housing and transportation choices, and reduce pollution caused by transportation. 

Plan Bay Area 2040 was adopted on July 26, 2017. Visit the Plan Bay Area website to learn more about how you can get involved.

Public comments like those collected during spring 2015's Plan Bay Area 2040 open houses and the virtual open house inform staff recommendations and, ultimately, the final decisions about Plan Bay Area 2040 made by MTC and ABAG. At key milestones in the development of Plan Bay Area 2040, staff summarized the input heard at open houses, as well as on our online forum and any emailed or mailed comments, for consideration by the boards of ABAG and MTC.
