All oversize loads entering the City of Gillette, Campbell County, must conform to the requirements set by the Wyoming Department of Transportation (WYDOT). WYDOT regulations supersede local ordinances, but Gillette has specific requirements for routes and local impacts.

In general, any vehicle exceeding 8 feet 6 inches in width, 13 feet 6 inches in height, or exceeding the legal weight limits for Wyoming highways should obtain an oversize load permit. For Gillette, this often applies to loads exceeding 80,000 lbs gross vehicle weight.

Loads destined for or originating from the industrial areas around the Energy Capital Sports Complex or the mines south of town will be subject to additional scrutiny regarding route selection to minimize impact on residential areas and school zones. Contact the Gillette Public Works Department for route approval prior to applying for a WYDOT permit.

Escort vehicles are typically required in Gillette when loads exceed 12 feet in width, 14 feet 6 inches in height, or extend more than 10 feet beyond the front or rear of the transporting vehicle. Specific requirements are determined by WYDOT on a case-by-case basis.

Local police escort requirements within Gillette are rare but may be required for extremely large or complex loads. Contact the Gillette Police Department's Traffic Division at (307) 682-5155 to discuss potential needs and associated fees (typically $75/hour per officer, with a 4-hour minimum). Scheduling is dependent on officer availability.

Documentation requirements include detailed load dimensions, vehicle information, proposed route, and proof of insurance. For loads impacting City infrastructure (e.g., requiring temporary removal of signs or traffic signals), a detailed plan and bond may be required.

Time-of-day restrictions may apply within Gillette, particularly during peak traffic hours (7:00 AM - 9:00 AM and 4:00 PM - 6:00 PM) on weekdays. Consult with the Gillette Public Works Department for specific restrictions based on your route.

Seasonal weight restrictions are common on some roads during the spring thaw (typically March-May). Check with WYDOT and the City of Gillette for current weight limits on specific routes.

Certain residential areas and school zones have restricted routes for oversize loads. Avoid routes through downtown Gillette and near schools during school hours. The Public Works Department can provide approved route maps.

WYDOT permit fees vary based on load size, weight, and distance. Expect to pay a base fee plus additional charges per mile for oversize dimensions or overweight loads.

Gillette does not typically charge a separate permit fee for route approval, but fees may apply for City services such as traffic control or infrastructure modifications (e.g., sign removal). These fees are determined on a case-by-case basis.
