Eastbound and Westbound- I-80 Fairfield Testing New Express Lanes Signs
Starts Friday, May 9, 9:00 AM-5:00 PM Mondays – Fridays
Motorists will NOT be Charged During Testing
SOLANO COUNTY – Caltrans and its transportation partner, the Metropolitan Transportation Commission (MTC) will be testing signage for the new I-80 Solano Express Lanes. The signs are located on eastbound and westbound I-80 between Red Top Road and Manuel Campos Parkway in Fairfield.
During testing, the signs will be illuminated with test messaging. The signage testing will occur starting Friday, May 9 until tentatively late summer 2025. Motorists will see test messaging on the signs each day beginning at 9:00 AM until 5:00 PM, Mondays-Fridays.
Motorists will NOT be charged to use the new far-left traffic lanes on I-80 in Fairfield and Vacaville during this testing phase. They will continue to be allowed to use the far-left traffic lanes on eastbound and westbound I-80 in Fairfield and Vacaville as a temporary car-pool lane during commute hours and use those same lanes as a traffic lane with no restrictions during non-commute hours.
After the testing phase is completed, sometime in late 2025, the signs will be activated and motorists using the new express lanes, the far left traffic lane, will be charged based on Express Lane charging criteria.
