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. Alameda CTC currently operates both the I-680 Sunol Express Lane (southbound over the Sunol Grade), and the I-580 Express Lanes (east- and westbound through Dublin, Pleasanton and Livermore).

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 Sunol (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. The next express lanes to open in the Bay Area are the I-680 Contra Costa Express Lanes between Walnut Creek and San Ramon, which are scheduled to open in Spring 2017 and are operated by MTC.

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+. Get a toll tag today. The I-680 Southbound express lane requires a FasTrak toll tag for solo drivers. Carpoolers on the I-680 Sunol Express Lane 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.

I-680 Sunol Express Lane southbound 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 Sunol Express Lane southbound has been in operation since September 2010. A northbound express lane along this same corridor is in the environmental documentation phase and is expected to begin construction in late 2017.
