Super loads - North Dakota

Loads over 18 feet wide, 18 feet high, 120 feet long, and/or 150,000 pounds are considered super loads.

When applying for a super load permit you must submit a letter stating that the load cannot be broken down and that it cannot be moved by any other mode of transportation. You must include a diagram of the vehicle, load and a certificate of insurance.

Bridge analysis if needed - $25.00

If over 18 feet wide, Highway Patrol may be required to escort. Fee: $50 per hour plus $.50 per mile.

If a load or vehicle movement exceeds 18 feet in width, the carrier must contact the NDHP commanders in the districts in which the load or vehicle is traveling. The receipt/permit will show the NDHP district(s) and phone number(s) so the carrier knows who to contact.

When an overheight load movement exceeds 18 feet, written authority is required from the utility companies (indicated on the permit).

When the overall length exceeds 120 feet, a pilot car is required to the rear.

When a load movement is made on a county highway system, permission is required from local authorities for that carrier to use the county system. The permit will generally list a phone number for that local authority.

Allow two to three days for processing.
