A single trip building and/or trunnion permit is required for all non-reducible, oversize and/or overweight load movements that exceed North Dakota legal vehicle size limits. Review the ND Legal Vehicle Size and Weight Guide and the ND Weight Limitations Chart for further information.
The online e-permits system accepts application for single trip permits for oversize/overweight loads movements. Axle weights shall not exceed maximum permitted limits. See the Building Moving Permit Policy or the Heavy Load Permit Policy for loads in excess of 200,000 pounds. The maximum weight on a tandem axle is 40,000 pounds and a single axle is 22,000 pounds when the GVW exceeds 150,000 pounds. If there are 8 tires per axle and additional weight is needed, it should be annotated in the miscellaneous tab in the remarks. Permit staff will change the weight on the axle once it has been submitted for review.
When exceeding 200,000 pounds gross or when there are 8 tires on an axle, a vehicle loading diagram must be uploaded in the routing portion of the permit. If the load exceeds 20 feet wide, a traffic control plan is required. The traffic control plan can be uploaded into the vehicle loading diagram.
A single trip permit is valid for one load movement up to five days.
