Bay Area transportation agencies are developing a 550-mile network of Bay Area Express Lanes that will be completed in 2035. MTC will convert 150 miles of existing High Occupancy Vehicle (HOV) lanes to express lanes and add 120 miles of new lanes to close network gaps. Ultimately, MTC will operate 270 miles of Bay Area Express Lanes.


  • Bay Area Express Lanes will:
  • Create a seamless network of HOV lanes to encourage carpools, vanpools and transit use,
  • Make the best use of HOV lane capacity,
  • Provide drivers with the choice for a more reliable travel option, and
  • Better manage lanes to keep traffic moving
