Wisconsin Oversize & Overweight Permits filed with WisDOT for you, 24/7

In Wisconsin, a load over 8 ft 6 in wide, 13 ft 6 in high or 80,000 lbs needs a WisDOT oversize/overweight permit. In spring, overweight permits stay off about 1,400 miles of Class II highway, and most divisible-load multiple-trip permits over legal weights are suspended. Send us the load and route: our permit desk quotes the price and files every permit the trip needs.
