Express lanes are specially-designated highway lanes that offer toll-free travel for carpools, vanpools, motorcycles, buses and eligible clean-air vehicles. Solo drivers also have the choice to pay to use the lanes to avoid congestion.

Bay Area transportation agencies are planning a 550-mile network of Bay Area Express Lanes by 2035. MTC will operate 270 miles of these lanes. The map below shows Bay Area Express Lanes at full build-out.

MTC Express Lanes

The Metropolitan Transportation Commission (MTC) and the Bay Area Toll Authority (BATA) have formed a Joint Powers Authority (JPA) to develop and operate their express lanes. The authority will convert 150 miles of existing High Occupancy Vehicle (HOV) lanes to express lanes and add 120 miles of new lanes to close system gaps; ultimately operating 270 miles of Bay Area Express Lanes.

The majority of the five voting members on the MTC express lane authority represent the three counties where these lanes are located: Alameda, Contra Costa and Solano. The authority will make policy and operational decisions, regarding toll rates, project phasing and use of revenue.
