Regional Transit Expansion Program

The Bay Area’s population is growing, particularly in urban neighborhoods, and the regional transit network must expand to keep up with this growth.

San Francisco Municipal Transit Agency

One of the Bay Area’s challenges is to balance the need for growth with the need to take care of existing transit systems.

MTC's Regional Transit Expansion Program (Resolution 3434) was last updated in 2008, and identifies the top priorities for new Bay Area transit projects. And it helps the region compete with other metropolitan areas for state and federal funding.

Some Regional Transit Expansion Program projects are now under construction:

  • BART extension to downtown San Jose
  • Caltrain Electrification

Other Regional Transit Expansion Program projects have already been completed:

  • Muni Van Ness Bus Rapid Transit
  • Muni Central Subway
