All oversize loads entering the City of Madison, Dane County, must conform to the requirements set by the Wisconsin Department of Transportation (WisDOT).

In general, any vehicle over 12 feet in width, 14 feet in height, and within the Class 3 weight category (over 120,000 lbs but not exceeding 150,000 lbs) should obtain an oversize load permit from the Madison Public Works Department.

The City of Madison requires permits for oversize loads to ensure safe transportation and minimize disruptions to local traffic and infrastructure. Permits help direct vehicles to the most efficient routes, avoiding damage to City facilities and unnecessary delays.

Escort vehicles are required in Madison for oversize loads exceeding 16 feet in width or 18 feet in height. Additionally, loads over 150 feet in length or those that require lane closures may need escort services.

Local police escorts may be required for particularly large or complex loads, especially those traveling through high-traffic areas or during peak commute hours. Scheduling and fees for police escorts should be arranged through the Madison Police Department's Traffic Management Unit, with a minimum of 48 hours' notice.

To apply for an oversize load permit in Madison, applicants can visit the Wisconsin Department of Transportation's online permit portal or contact the Madison Public Works Department directly. Required documentation includes detailed load specifications, proposed route, and travel dates.

Applicants must also provide proof of insurance and a valid USDOT number if applicable. The Madison Public Works Department reviews applications to ensure compliance with local regulations and route restrictions.

Oversize loads in Madison are subject to time-of-day restrictions, typically avoiding peak commute hours (7-9 am and 4-6 pm, Monday-Friday).

Seasonal restrictions may apply during periods of heavy snowfall or road construction, particularly on highways like US-12 and US-18. Loads may need to be routed around construction zones.

Certain neighborhoods, such as the historic districts around the State Capitol and University of Wisconsin campus, have restricted routes to minimize disruptions. Loads should be planned to avoid these areas whenever possible.

The base permit fee for an oversize load in Madison is $60. Additional fees apply based on the complexity of the route and any required escort services.

For example, police escort services are billed at $100 per hour, with a minimum of 2 hours. Complex routing that requires additional review may incur a $200 review fee.
