Idaho Weigh Station Closed for Construction Through 2027
The Idaho Transportation Department has closed the Lower Lewiston Port of Entry to allow for construction and facility upgrades. The closure affects drivers traveling east of Lewiston on U.S. Highway 12 and U.S. Highway 95.
On May 18, the department announced that the facility would remain closed through early 2027. The decision was made to support long-term improvements at the site, which serves as a weigh station and inspection point for commercial vehicles.
During the closure, trucks that normally would have been weighed and inspected at the Lower Lewiston Port of Entry will need to use alternative routes or facilities. The department has not yet released specific details on temporary enforcement locations or rerouting options.
Ports of Entry in Idaho perform several functions for commercial drivers. They check vehicle weights, dimensions, and safety compliance, and they collect data used for planning and enforcement. A prolonged closure at one site can shift enforcement activity to other locations along the corridor.
The Lower Lewiston facility sits at a key junction where U.S. 12 and U.S. 95 meet. This area handles traffic moving both north-south and east-west, including loads traveling through the state from neighboring Washington and Montana. When a station in this location is closed, trucks that previously stopped here may pass through without the usual checks until they reach another active facility.
Idaho maintains several Ports of Entry across the state. Each site contributes to a statewide network that helps ensure compliance with state and federal regulations. Upgrades at individual locations are part of ongoing efforts to modernize equipment and improve operational efficiency.
Drivers who regularly travel through the Lewiston area should monitor official announcements from the Idaho Transportation Department for updates on enforcement changes during the construction period. Temporary signage or electronic message boards may appear near the closed site to direct traffic.
The department has indicated that the project will address both structural needs and operational improvements at the facility. Once construction is complete, the station is expected to reopen with updated equipment and layout.
