Super loads

Super loads are defined as a load that is greater than one of these dimensions: 16' wide, 16" high, 150' long and/or 250,000 pounds or fails the overload analysis.

In order for the office to consider pre-approval the following items are required:

  • A letter of request detailing all information that would attempt to justify a permit, such as but not limited to reasons why the product could not be reduced or shipped by other modes of transportation such as rail or barge.
  • Load dimensions
  • A detailed shop drawing, specification sheet or plans showing both a longitudinal and a transverse view of the entire axle configuration including truck-tractor with axle spacing’s and weights on each axle in U.S. measurements.
  • A certified scale ticket for loads with weight.
  • A detailed route survey locating all points of contact and means of avoiding such contact points.
  • Minimum two police escorts (front and rear) for loads in excess of 16' ft wide or high. The Alabama Trooper Association will facilitate the scheduling of the escorts and should only be contacted AFTER permit office pre-approval has been confirmed.
  • Utility notification for loads over 16' 6" high: power company, cable company, telephone company, and traffic signal owners.
  • City or County Engineers approval required when traveling city or county roads.
  • ALDOT may require additional insurance coverage as security to compensate the State of Alabama for any injury to any public road or bridge on the Superload route.

Escort vehicle requirements can differ significantly by state in terms of mandatory driver qualifications, training, certifications, vehicle weights, obligatory signage/flags/lighting, necessary onboard equipment, and more. The ODS team can provide you with all additional requirements specific to your route.
