I-80 Eastbound Cordelia Truck Scales Relocation Project

This Project Has Been Completed


New Eastbound I-80 Scales Open To Truck Traffic

The new Interstate 80 eastbound Cordelia Truck Scales opened to truck traffic on August 1, 2013.

  • A Ribbon Cutting ceremony for the new facility was held on July 12, 2013.

  • The California Department of Transportation (Caltrans), the Solano Transportation Authority (STA), the Metropolitan Transportation Commission (MTC), and the California Highway Patrol (CHP) broke ground on the project on April 20th, 2012.
  • The demolition of the old eastbound scales facility was completed in the fall of 2013.
  • The project and its project partners Caltrans, the Metropolitan Transportation Commission (MTC), and CHP were awarded the “2013-Special Achievement” award by the STA.
Project Snapshot

The eastbound I-80 Cordelia Truck Scales Project reconstructed and modernized the old eastbound scales built in 1958. The project also included the construction of a four-lane bridge across Suisun Creek and new braided on and off ramp access between the new eastbound Truck Scales, I-80 and nearby Highway 12.

The new, nearly $100 million complex will make it more efficient for CHP to conduct safety inspections and improve technology.

The new eastbound facility was constructed approximately 2,500 feet east of the old 1958 facility site and will accommodate the projected increase of traffic along I-80 through 2040. In spring 2012, nearly 10,000 trucks a day traveled from the Port of Oakland along I-80 to Northern California and beyond.

Features and Benefits

The new truck scales facility also improves traffic safety and travel times along the busy I-80/I-680/Highway 12 corridor in Solano County by improving:
  • Truck inspection times with modern state-of-the-art weigh-in-motion technology. The new scales will make it easier for the CHP to weigh trucks entering the scales.
  • Inspection capability of trucks with multiple loads. The new facility will include new multiple truck inspection bays, making it easier and more efficient for the CHP to conduct routine inspections.
  • Traffic flow of trucks entering and exiting the new facility. The new scales will be constructed with newly designed traffic lanes using a system of braided ramps which will improve the safety of all vehicles entering and exiting the facility as well as improve traffic flow along the I-80/I-680/Highway 12 corridor.
The project received 50 percent of its funding from the State Highway Operation and Protection Program and 50 percent from regional/local funds.
