I-680 Sunol Express Lanes (between SR-84 to SR-237)
Tolling began on I-680 Sunol Express Lanes on March 31, 2023. All drivers need a FasTrak® transponder to travel in the express lanes during operating hours (Monday through Friday, 5 a.m.-8 p.m.). Carpoolers with two or more occupants can travel toll-free with a FasTrak Flex. Eligible Clean Air Vehicles with one occupant will receive a 50% discount with a FasTrak CAV toll tag. Express lanes will be open to all traffic outside of operating hours.
The I-680 Sunol Express Lane is governed by the Sunol Smart Carpool Lane Joint Powers Authority, and was funded with State, Federal, and local funds. Alameda County’s voter-approved local sales tax Measure B provided nearly half the funding for the Express Lane. Usage of the express lane has increased steadily since inception.
