Westbound I-80 Express Lane Opens as Temporary HOV Lane Ahead of Formal Launch in Late 2025
Temporary HOV Lane Opened to Traffic on Saturday, March 8
SOLANO COUNTY – The future westbound Interstate 80 (I-80) express lane running between Vacaville and Fairfield is now temporarily open to High-Occupancy Vehicle (HOV) traffic as of Saturday, March 8.
Roadway construction on the new express lane is ongoing and electronics and hardware for collecting tolls are still being installed. In the meantime, this lane is available to vehicles with two or more people on board weekdays from 5:00 a.m. to 10:00 a.m. and 3:00 p.m. to 7:00 p.m. During non-weekday commute hours, the lane is open to all motorists.
The new temporary HOV lane runs on westbound I-80 from the Interstate 505 interchange in Vacaville to Airbase Parkway in Fairfield.
As work is still in progress, we ask motorists to please be mindful of their speed for the safety of our workers. Caltrans and its transportation partners expect to formally launch the completed express lane by late 2025. At that time, motorists using the new traffic lane will be charged as appropriate.
