Super load information for Alabama.

Alabama state DOT will classify any shipment in excess of the following as a super load:

Defined as shipments in excess of any of the following dimensions/weights; over 250,000 pounds (113398.0 kilograms) of gross weight, over 16 feet (4.87 meters) in width, over 16 feet in height, over 150 feet (45.72 meters) long. Anything of this nature will require special ALDOT approval. Detailed drawings will be required and need to include shop drawings of the item being shipped, the truck and trailer axle weights and spacings for both truck tractor and trailer. A letter from the manufacturer is required certifying the shipment is reduced to the lowest possible size and weight configuration as well as an explanation of why it can not be shipped by other means such as by barge or port. Loads exceeding 150,000 pounds (68038.8 kilograms)are subject to a full scale structural bridge analysis if bridges are in the route. A special weight authorization (SWA) is required from the permit office to initiate the necessary bridge rating section investigation as well. Night travel (9PM – 6AM) may be required with a state trooper or police escort (minimum of 2 when travelling). A route survey will probably be required. The Alabama State Troopers Association handles all of the scheduling of police/trooper escorts after your super load permit has been issued. A lighting system configured from strobe warning lights must be placed on each extremity of the shipment in addition to basic requirements such as flags and oversize load signs. All rail road crossings must be identified and railroad must be notified in advance of your intent to cross as well as date and time. ALDOT will more than likely verify this with the railroad and not issue a super load permit until verified. It is the carriers responsibility to notify the railroad of each intended crossing. At each rail crossing you will find a small plaque with a phone number and a “crossing number” that identifies each crossing for submitting cross requests. A bucket truck is required to accompany loads that exceed 16 feet and 5 inches (5.0 meters) in height and it is the carriers responsibility to show proof of “utility notification” for shipments in excess of 16 feet and 6 inches (5.02 meters) in height. City or county approval is required for Alabama super loads as well, please see the Alabama list of county engineers for contact details. For information published by the state you can read more Alabama super load information.
