New Tolling Policies Announced for I-680 and I-580

The Alameda County Transportation Commission (Alameda CTC) and the Interstate 680 Sunol Smart Carpool Lane Joint Powers Authority (I-680 Sunol JPA) today announced that beginning Friday, March 31, 2023, tolling would resume on the I-680 Sunol Express Lanes, and new toll policies for clean air vehicles (CAVs) would be in effect on both the Interstate 580 (I-580) Express Lane and the I-680 Express Lanes in Alameda County.

Beginning Friday March 31, I-680 express lanes will resume operations between 5:00 a.m. and 8:00 p.m. from Monday to Friday. FasTrak® is required for ALL express lanes users, and drivers are encouraged to get a FasTrak Flex® toll tag for carpooling or a FasTrak® CAV toll tag for CAVs. Carpools of 2 or more occupants and motorcyclists can continue to use the lanes for free with a FasTrak Flex® toll tag. Visit to find out how to get your FasTrak® toll tag.

“Express lanes increase the efficiency of our transportation system for commuters, transit and freight. They offer solo drivers the option to pay a toll for access into the carpool lanes when there is excess capacity, thereby enhancing efficiency of the corridor, and qualified carpools continue to use the lanes for free,” says Alameda CTC Executive Director Tess Lengyel.

Solo drivers in other vehicles can use the express lanes with FasTrak Flex® for a more reliable trip and pay full price. Tolling, lane access restrictions, and better enforcement improve traffic flow, keeping vehicles moving. This gives carpoolers and others who choose to use the lanes a more reliable trip than regular high-occupancy vehicle lanes.
