Regional Transit Expansion Program

The Bay Area’s population and urban neighborhoods are growing – and our regional transit network must expand to keep up with this growth.

How can we best expand our network while still maintaining and operating the trains, buses, ferries, tracks, stations and other assets we already have?

MTC is meeting the challenge, and has been for years.

The Regional Transit Expansion Program – or Resolution 3434 – identifies the top priorities for new Bay Area transit projects.

And it helps our region compete with other metro areas for state and federal funding.

Current transit expansion projects include:

  • AC Transit Oakland-San Leandro Bus Rapid Transit
  • BART to Warm Springs/Milpitas/San Jose
  • e-BART extension in East Contra Costa County
  • San Francisco Muni Central Subway
  • Sonoma-Marin Area Rail Transit
  • San Francisco Transbay Transit Center
