I-80 WESTBOUNDCordelia Truck Scales Improvements

INTERSTATE

80The proposed project will replace the existing Cordelia Truck Scales along Westbound I-80 in Solano County. The existing truck scales facility was constructed in 1958 to inspect trucks entering the San Francisco Bay Area from locations nationwide, and accommodates between 500 and 700 trucks per day. lt consists of two dynamic and one static scale, four inspection bays, and limited parking. The existing facility is outdated, under capacity, and does not include state of the art technology required for truck inspections today. Existing access from l-80 consists of short on and off ramps, resulting in truck traf�c backing up onto I-80 and increasing the potential for rear-end accidents. During peak traf�c periods experienced several times per week, the facility is closed to incoming trucks to prevent this queuing.

The new truck scales facility will be relocated 0.7 mile east from its current location and will provide a new braided off-ramp connection and new entrance ramp connection to/from Westbound I-80. Direct access to the facility will also be provided from westbound State Route 12 (East). The new facility will have the capacity to inspect all westbound I-80 trucks passing the facility 24 hours per day, seven days a week.

The new facility will be a Class B Commercial Vehicle Enforcement Facility (CVEF), which is de�ned as an independent command facility of the CHP. Key aspects of the facility will consist of the following:

Seven covered inspection areas with con�gurations to accommodate long vehicle combinations.

Inspection areas with the capability to inspect the underside of low-clearance vehicles.

Elevated structures to enable inspectors to check the domes and top portions of cargo trucks.

"Weigh In Motion" scales with the capability to sort truck traf�c into the appropriate lane along the approach roadway.

A minimum of four sets of scales to accommodate two lines of empty and loaded trucks.

Constructing and opening the full Westbound Cordelia Truck Scales will result in the following enhanced bene�ts:

Increased processing capacity of the truck scales to up to 1000 trucks per hour

Increased queue capacity and a reduction in congestion

Reduction in rear-end accidents along I-80

A fully modernized and state of the art truck scales facility for westbound 1-80

Auxiliary inspection areas for potentially hazardous trucks will improve public safety

Improved corridor operations by increasing weaving distances between adjacent interchanges
