I-90 - Spokane Port of Entry-Weigh Station Relocation - Complete September 2011

The previous Port of Entry scale site was constructed in the mid 1970's and was out of date with today's technology. The new scale site is equipped with Weigh-In-Motion (WIM) system. This allows the trucks to be weighed on I-90 at highway speeds without stopping at the scales unless directed to. Another feature that will be added is the NORPASS system. This allows the WSP to monitor information electronically through a database about the truck with out stopping the truck. With the additions of the WIM system, the NORPASS system, an inspection building, and additional parking for out of service vehicles, the Port of Entry needed to be moved so that all of these components are located in the State of Washington.

How You Benefit
Car GlyphRelieves Congestion
The relocation of the scale site results in fewer trucks needing to stop at the scales. It also results in improving traffic flow along Interstate 90 and in the Idaho Road Interchange since the trucks have their own dedicated exit to the new weigh station if they are required to stop.
