A bill for an act relating to certain state highways not designated as part of the interstate road system, including the operation of implements of husbandry on such highways, making appropriations, and including applicability provisions.

HF 394 restricts the Department of Transportation from designating a segment of State Highway 5 and US Highway 65 as an interstate unless federal exemptions for vehicle weight and size are secured. It creates a temporary exception, allowing implements of husbandry to continue operating on a specific portion of this highway if it becomes an interstate, until a suitable alternative route is established. The bill appropriates $250,000 to the Department of Transportation to study and develop this alternative highway route for agricultural vehicles. These provisions directly affect the Department of Transportation's authority over highway designations and agricultural vehicle operators in the specified areas.
