Superload information.
The following would qualify a shipment as a superload in the state of Alabama:

Defined as shipments in excess of any of the following dimensions/weights; over 250,000 lbs in gross weight, over 16’in width, over 16′ in height, over 150′ 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 lbs. 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 superload 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 superload 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′ 5″ in height and it is the carriers responsibility to show proof of “utility notification” for shipments in excess of 16′ 6″ in height. City or county approval is required for Alabama superloads as well, please see the Alabama list of county engineers for contact details. Superload requirements by the ALDOT can be read here.

  1. Alabama oversize and heavy haul shipping rules and regulations updated May 21, 2018.

  2. What is the wind rile in Alabama please.

    • “Wind Rife” ?

      • Could you please further explain your question please? At the moment we have not heard about any laws that involve measuring “wind” speeds and have assumed this up to the discretion of the driver. We’ll be happy to further research it for you but want to make certain we clearly understand the question. Thank you for your time.

  3. Yes. Anything over 8’6″ is required to be permitted in order to transport.

  4. What are the calculations for oversized loads on steep mountain grade roads for rate of speed and time to stop at a red light placed at bottom of steep grade? What should the length of a yellow light? What type of safety notifications for changing lights are required?

    • Well, firstly pardon the delay as you got caught in a huge amount of posting spam. However once cleared out, there you were Dr. Richards. So, to be direct as possible this is a pretty isolated incident however does occur. So, “oversize” wouldn’t have a huge effect on the capabilities of the vehicle to stop. However, weight would. And this is yet another reason besides creating stress cracks in roads that extra axels are required in most of the world in order to be eligible to ship heavy haul items (in NA over 80,000 lbs GVW). With the extra axels you get that many more brake pads and shoes as well. Any experienced driver which is usually what it takes to set behind the wheel of something so drastically expensive (some over 1 mil overall) would know what speed to take the approach with which would probably be very slow. The brakes combined with the axles are designed to accommodate the maximum weight allowed on the trailer so failure would be an extreme. In certain circumstances either the state would require or the carrier may request a traffic control officer at the light. In the event one was not requested or required the driver would simply call a yellow (and probably even a green) light a red one and come to a complete stop before continuing. Yet another reason newbies drive $100,000 rigs and heavy haul drivers are well seasoned with most over 20-30 years in the industry. It’s a pecking order that is determined by either how much money you have saved (which takes a lot of years) or how much verifiable experience you have as word of mouth probably couldn’t get you in the passenger seat let alone behind the wheel. I hope this helps you.
