Unlocking Travel Possibilities with a Second Transbay Crossing
To amplify rider connection and benefits already planned by our partner agencies across the Megaregion, Link21 is planning a second underground train crossing between San Francisco and Oakland/East Bay to accommodate Regional Rail, BART, or perhaps both in the future. Concepts will be developed, evaluated, and refined to identify project(s) to move forward into environmental review.
We’re Reimagining Rail
We kicked off Phase 1: Project Identification in early 2022. Over the next two years the Program will work closely with partners, stakeholders, and the public to explore project concepts.
Northern California Residents on the Move
To understand current travel needs, key destinations to which our residents are traveling, and how population growth will impact future travel, Link21 conducted a Market Analysis, the most detailed and comprehensive travel analysis ever performed for the 21-county Northern California Megaregion.
A Solid Foundation Centered on Equity Guides Planning
Our strong partnerships with community members, organization leaders, agency partners, technical specialists, and other key leaders across the Megaregion will continue to grow as we work together for a better, more equitable future. Learn more about what we’ve accomplished thus far.
