Interstate-80/Interstate-680/Highway 12 Interchange Project-Fairfield
Increased Construction Activities resume-September 2015

SOLANO COUNTY – The California Department of Transportation (Caltrans), and its project partner the Solano Transportation Authority (STA) are continuing work on the Interstate-80/Interstate-680/Highway 12 Interchange Project in Fairfield.

Crews are now performing drainage work near the Green Valley Road/Interstate-80 (I-80) overcrossing. The work requires intermittent daytime lane closures on the overcrossing and its approach on Green Valley Road as heavy equipment enters and exits the construction site. Motorists should watch for flaggers and expect delays.

The drainage work is scheduled to start at 8:30 AM until 5:00 PM Monday through Friday. The water line work on Green Valley Road is scheduled to be completed by the afternoon of Friday, September 4. Crews will return to complete water line work in the vicinity of Green Valley Road at a future date to be announced.

Construction in this area is expected to be ongoing for the next six months. During heavy construction periods, motorists should also consider using alternate routes.

Southbound Green Valley Road/Lopes Road (I-80 overcrossing)
Alternate route:
Motorists heading southbound on Green Valley Road/Lopes Road are advised to use eastbound Business Center Drive, southbound Suisun Valley Road, then southbound on Central Way, eastbound on Old Cordelia Road, and southbound on Lopes Road.

I-80/I-680/Highway-12 Project Improvements:
The work which started in June 2014 is part of the I-80/I-680/Highway-12 Interchange project. During this first phase, a new Green Valley Road overcrossing will be constructed above I-80 about 200 feet east of the existing overcrossing.
