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 (opened in September 2010) and I-580 (opened in February 2016), 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 Santa Clara 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 I-580 Express Lane users, and in order to travel toll free on the I-580 Express Lane, carpoolers need to have a FasTrak Flex toll tag set to 2 or 3+.

Carpoolers on I-680 currently do not need a toll tag, but can use the new FasTrak Flex toll tag set to 2 or 3+, or place their standard toll tag in a mylar bag to avoid being charged a toll.
