The I-680 Contra Costa Express Lanes are scheduled to open in late September or early October. Toll system testing will continue through opening, The tests confirm that toll prices are properly calculated and displayed on highway signs, that toll tags are properly read as they pass under the tolling equipment and that the data from tag reads is properly accumulated to produce accurate charges to drivers’ accounts and protect privacy. 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.
The “under construction” labels on the overhead signs will start to come down prior to the lane opening. As these labels are removed, information will be placed on variable toll messaging signs to indicate that the lanes are not yet functioning as express lanes.
