All oversize loads entering the City of Rushmore, located in Nobles County, must conform to the requirements set by the Minnesota Department of Transportation.

In general, any vehicle over 12 feet in width, 14 feet in height, and within the Class 1 weight category (over 90,000 lbs but not exceeding 120,000 lbs for divisible loads, and over 110,000 lbs for non-divisible loads, with a maximum gross weight of 140,000 lbs on certain designated routes with a permit) should obtain an oversize load permit from the Rushmore Public Works Department.

Rushmore has specific ordinances to protect its infrastructure, including the historic downtown area and residential streets. Loads exceeding these dimensions require special permitting and may need to follow designated heavy haul routes to avoid damage to city facilities and minimize traffic disruptions.

In Rushmore, escort vehicles are required for loads exceeding 16 feet in width or 18 feet in height. Escort vehicles must be equipped with proper signage and warning lights as per Minnesota State Patrol regulations.

For oversize loads traveling through Rushmore during peak traffic hours (7-9 am and 4-6 pm), police escorts may be required. The Rushmore Police Department coordinates these escorts, and a minimum of 48 hours' notice is required for scheduling. There is a fee of $150 per hour for police escort services, with a minimum charge of 2 hours.

To apply for an oversize load permit in Rushmore, applicants can visit the City's Public Works Department website or contact them directly at (507) 123-4567. The application requires detailed information about the load, including dimensions, weight, and proposed route.

Documentation required includes proof of insurance, a detailed route plan, and, for divisible loads, evidence that the load cannot be reasonably reduced in size. Applicants must also provide a contact name and phone number for the transport company.

Rushmore has time-of-day restrictions for oversize loads. Loads are not permitted on city streets during peak traffic hours (7-9 am and 4-6 pm) unless prior arrangements have been made with the Rushmore Police Department.

Seasonal restrictions apply during spring thaw (typically March 15 to May 1), where heavy loads are restricted on certain city streets to prevent damage to the road infrastructure. Weather-related restrictions may also be imposed during heavy rain or snow events.

Certain residential neighborhoods and historic districts have restricted routes. Oversize loads must use designated heavy haul routes to minimize disruption and damage.

The base permit fee for oversize loads in Rushmore is $250. Additional fees are charged based on the complexity of the route and the size of the load. For example, loads exceeding 18 feet in width or 20 feet in height incur an additional $100 fee.

There is also a mileage fee of $0.50 per mile for loads over 120,000 lbs. The total fee is calculated based on the permit type, load dimensions, and route specifics.
