WisDOT
The Wisconsin Department of Transportation (WisDOT) was officially established in 1967 by combining formerly independent agencies and the Department of Motor Vehicles (which included the State Highway Commission, State Aeronautics Commission and State Patrol).
WisDOT supports all forms of transportation. The department is responsible for planning, building and maintaining Wisconsin’s network of state highways and Interstate highway system.
