All oversize loads entering the City of Manitowoc must conform to the requirements set by the Wisconsin Department of Transportation (WisDOT). Oversize and overweight permits are required for vehicles exceeding legal limits.

In general, any vehicle over 8 feet 6 inches in width, 13 feet 6 inches in height, and exceeding 80,000 pounds gross vehicle weight should obtain an oversize load permit from the WisDOT and potentially the Manitowoc Public Works Department if local routes are impacted.

Specifically, loads traversing through or near the Port of Manitowoc area, or impacting designated truck routes like Maritime Drive (Highway 42) should pay close attention to bridge weight restrictions and height clearances. Coordination with the City Engineer's office is recommended for routes near the Manitowoc River crossings.

Escort vehicles are typically required in Manitowoc when a load exceeds 12 feet in width, 14 feet 6 inches in height, or 100 feet in length. Specific situations such as limited visibility or congested areas may also necessitate an escort.

Local police escorts in Manitowoc County are generally required for loads exceeding 14 feet in width or height, or those requiring lane closures on state highways within the city limits. Requests for police escorts should be made through the Manitowoc County Sheriff's Department at least 72 hours in advance. Fees vary based on the duration and complexity of the escort.

Applications for oversize/overweight permits in Manitowoc are primarily handled through the Wisconsin DOT e-Permitting system. For routes impacting city streets, a secondary permit or notification to the Manitowoc Public Works Department (920-686-6900) may be required.

Documentation requirements include a detailed route plan, vehicle dimensions, weight distribution, and proof of insurance. For loads impacting city infrastructure, a structural analysis may be requested by the City Engineer to ensure bridge and road capacity.

Time-of-day restrictions may apply to oversize loads traveling through Manitowoc, particularly during peak traffic hours (7:00 AM - 9:00 AM and 4:00 PM - 6:00 PM) on weekdays. Restrictions are more stringent near schools and industrial parks.

Seasonal weight restrictions are often in place during the spring thaw (typically March-April) on certain city streets to prevent damage to the pavement. Check with the Manitowoc Public Works Department for current restrictions.

Certain residential areas and narrow streets in downtown Manitowoc may be restricted to oversize loads. Routes along Lake Michigan should also be carefully planned due to potential wind conditions. Avoid routes through Washington Park if possible.

Permit fees for oversize loads in Manitowoc are based on the Wisconsin DOT's fee schedule, which considers factors such as weight, distance, and number of axles. City-specific permits, if required, may incur additional fees.

Fees vary significantly depending on the load dimensions and route complexity. For example, a load requiring bridge reinforcement analysis will likely incur higher fees.
