The lanes will operate Monday through Friday from 5 a.m. to 8 p.m. During times when traffic is light, tolls will automatically adjust lower so that traffic in the corridor flows across all the lanes and additional congestion is not created. The Metropolitan Transportation Commission (MTC), which operates and manages the I-680 Contra Costa Express Lane, will continuously monitor lane operations to ensure that traffic flows the best it can.
All-day operating hours encourage and reward carpooling whenever there is congestion, which often happens outside the peak commute hours. The goal of express lanes is to get more people, not just cars, where they need to go. The hours are also consistent with neighboring lanes on I-680 and I-580 in Alameda County to limit driver confusion.
All drivers must have FasTrak® to use the lanes between 5 a.m. and 8 p.m. Carpools must have a FasTrak Flex® toll tag to use the lanes toll-free. With all-day hours of operation, be sure to consider all of your travel when selecting your FasTrak toll tag. Solo drivers need a standard FasTrak or FasTrak Flex toll tag to pay to use the lanes between 5 a.m. and 8 p.m.
Testing of the electronic toll signs and the toll system continues through opening. Motorists can expect to see dots, test toll amounts, and notification that testing is underway on the electronic signs. All toll system signs are affixed with static “Under Construction” stickers. While motorists will see prices on the signs, cars will not be tolled during the tests. Nighttime lane closures on I-680 continue throughout the next month.
