Weigh Station Capital Improvement Program

Scoring criteria for the weigh station capital improvement program. Out of 100 possible points, 25 points are based on enforcement and safety, 20 points are based on condition, 20 points are based on roadway characteristics, 20 points are based on freight, and 15 points are based on geographic coverage.

The Weigh Station Capital Improvement Program funds the installation, repair and replacement of the physical infrastructure necessary for the enforcement of state and federal weight and size commercial motor carrier laws. MnDOT is responsible for the physical infrastructure used to perform enforcement. The Minnesota State Patrol, a division of the Minnesota Department of Public Safety, is responsible for operations and carrying out of enforcement of the laws. The two units of government coordinate closely to identify operational and capital improvements.

Projects are solicited through MnDOT District offices and through input from the Weight Enforcement Unit of the State Patrol. MnDOT and the State Patrol are developing a 10 year Weight Enforcement Investment Plan that will identify and prioritize needs throughout the state. The plan will be the basis for project identification and selection.
