Wisconsin Oversize & Overweight Permits for Heavy Haul

Wisconsin permit rules, legal limits and escort triggers, and how we book heavy haul carriers for moves in and through the state.

Quick answer

Do I need a permit to move an oversize load in Wisconsin?

Yes, once the load is wider than 8 ft 6 in, taller than 13 ft 6 in or heavier than 80,000 lbs gross, and Wisconsin allows no scale tolerance on that weight. WisDOT issues single trip permits online: $20 for overwidth or overheight, $25 for both, and $20 to $85 for overweight up to 150,000 lbs. Local roads need the county or town's own permit.

Heavy haul and oversize freight in Wisconsin

Wisconsin's heavy freight runs between Milwaukee's machine shops, the paper mills of the Fox Valley and dairy country, and much of it is headed to or from Chicago and the Twin Cities. I-94 links Milwaukee, Madison and Eau Claire, I-41 and I-43 run north to Green Bay, and I-39/90 carries traffic down to the Illinois line. We book carriers for factory equipment, farm machinery and construction machines moving inside the state or across it.

Timing shapes a Wisconsin quote more than distance. Loads over 12 ft wide pause from Saturday noon to Sunday sunrise and for holiday periods that include both gun deer season weekends in November, and oversize loads keep off the Milwaukee County Expressway at rush hour. In spring, overweight machines must avoid about 1,400 miles of Class II state highway while the frost comes out, so we check the route against the current restrictions before pricing.

What are the legal size and weight limits in Wisconsin?

Under the oversize load regulations in Wisconsin, a load above any of these limits needs a state oversize or overweight permit.

Width 8 ft 6 in
Height 13 ft 6 in
Semitrailer length 53 ft
Gross weight 80,000 lbs
Single axle 20,000 lbs
Tandem axle 34,000 lbs

Limits are set by Wis. Stat. 348.05 to 348.15, with no enforcement tolerance on weight. County and town roads designated Class B allow only 60% of these axle and gross weights.

Who issues Wisconsin oversize permits?

WisDOT's Oversize-Overweight Permit Unit in Madison issues single trip permits through its online system, where most applications are analyzed and approved automatically. A single trip permit is good for 5 days on the route it names, a return trip on the same route costs nothing extra when it is requested with the application, and the permit can be ordered as much as 5 days before the move.

The state permit covers only State, US and Interstate highways. A pickup at a farm, quarry or plant on a county or town road needs a permit from that road's maintaining authority, such as the county highway commissioner, and the carrier's permit service files both.

What do Wisconsin oversize and overweight permits cost?

  • request_quote Single trip, oversize only: $15 for overlength, $20 for overwidth or overheight, $25 for both.
  • request_quote Overweight, including any oversize: $20 up to 90,000 lbs and $35 up to 100,000 lbs, then $10 more for each further 10,000 lbs, reaching $85 for 140,001 to 150,000 lbs.
  • request_quote Over 150,000 lbs: $85 plus $10 for every 10,000 lbs or part of it, and a WisDOT bridge review billed at $10 per employee-hour.
  • request_quote Over 16 ft wide: a $10 route review for each WisDOT region the trip crosses.
  • request_quote Wisconsin charges no ton-mile or separate superload fee. State Patrol escort time is billed to the carrier, including escorts cancelled late.

Worked example: a 172,000 lb lowboy load across Wisconsin

The gross is 22,000 lbs over 150,000, which counts as three 10,000 lb steps, so the permit is $85 + 3 x $10 = $115. WisDOT adds its bridge review at $10 per employee-hour, and if the load is also over 16 ft wide, $10 for each region on the route.

Seasonal weight limits in Wisconsin

Wisconsin runs spring weight restrictions by zone. When the thaw reaches 6 in below the pavement, WisDOT closes about 1,400 miles of Class II state highway to non-divisible overweight permits, and roughly 170 miles are posted at 6 tons per axle, 10 tons per tandem and 24 tons gross. The season averages early March to early May, no single trip permit overrides it, and counties and towns post their own roads.

FAQ

Wisconsin Oversize Load Questions

Permits, escorts and travel rules for oversize moves in Wisconsin.

How much is a Wisconsin oversize permit?
A WisDOT single trip permit costs $15 for a load that is only too long, $20 when it is too wide or too tall, and $25 when it is both. Overweight permits start at $20 up to 90,000 lbs and reach $85 at 150,000 lbs, with $10 added for each 10,000 lbs beyond that. Local road permits are priced by each county or town.
Can oversize loads travel at night in Wisconsin?
Some can. A load up to 12 ft wide, 13 ft 6 in high and 150 ft long may run after dark in most counties, subject to the evening limits in Columbia, Dane, Milwaukee, Rock and Waukesha counties. Anything larger moves in daylight only, and loads that are overweight but legal in size may travel around the clock.
When does a Wisconsin load need an escort?
WisDOT's chart combines width and length. A 13 ft wide load needs no escort until it passes 110 ft long, while a load over 15 ft wide takes at least one private escort. Law enforcement joins once a load passes 18 ft in width, 200 ft in length or 350,000 lbs, and anything taller than 16 ft adds a pole vehicle.
What are Class II roads in Wisconsin?
Class II roads are about 1,400 miles of state highway with soft subgrade that WisDOT restricts during the spring thaw, usually from early March into May. While the restriction is on, non-divisible overweight permits must route around those segments and most divisible-load multiple trip permits are suspended. Status and maps are on WisDOT's seasonal weight restrictions page.
Does a WisDOT permit cover county and town roads?
No. A WisDOT single trip permit is valid only on State, US and Interstate highways. The county highway commissioner, or the city, village or town engineer, issues permits for local roads and may add conditions and fees, so a move from a farm or job site off the state system needs two permits.
