Express Lanes

Express lanes are specially designated highway lanes that are toll-free for carpools, vanpools, motorcycles, buses and eligible clean-air vehicles. Solo drivers can choose to pay a toll using a FasTrak® or FasTrak® Flex toll tag to access the lanes for reliable travel times.

Express lanes increase the efficiency of our transportation system for commuters, transit and freight, by taking advantage of existing capacity to reduce congestion and improve air quality - giving solo drivers the option to pay a toll for access into the carpool lanes when there is excess capacity.

Alameda County is home to two express lane corridors: I-680 and I-580, both part of the larger Bay Area Express Lanes Network in development by the current and future express lane operators including Alameda CTC, Metropolitan Transportation Commission (MTC), the Valley Transportation Authority (VTA) and in collaboration with the Contra Costa Transportation Authority and the Solano Transportation Authority. Upon completion in 2035, the Bay Area will have 550 miles of express lanes operated by Alameda CTC, MTC, and VTA.

A Fastrak toll tag is required for ALL express lane users.

I-680 Southbound Carpool/Express Lane from Pleasanton to Milpitas

Located along a 14-mile stretch of southbound I-680 from State Route 84 south of Pleasanton to State Route 237 in Milpitas, the I-680 Southbound Express Lane has been in operation since September 2010. A northbound express lane along this same corridor is in the environmental documentation phase.
