I-80 Truck Scales Inspection Facility & Highway Interchange

I-80 Truck Scales Inspection Facility & Highway Interchange

Project Details:

Rebuild and relocate the existing eastbound Cordelia Truck Scales on I-80, in Solano County, within the I-80/I-680/SR-12 Interchange complex. A 4-lane bridge was built across Suisun Creek and braided ramps now connect the new scale facility to Eastbound I-80 and Eastbound SR-12 ramps. The E80-E12/E80 tunnel-like separation structure is approximately 300 FT long allowing E80 trucks exiting the new scale facility to travel under E12 traffic without cross traffic congestion. Paving will included approximately 5,848 tons of rubberized asphalt.

The California Highway Patrol now occupies a new 29,052 SF building of which 16,822 SF is inspection bays for trucks. It was designed per the requirements for the Silver Leadership Certification in Energy and Environmental Design (LEED) and includes state-of-the-art technology.
