The combination of length, width, height and weight are needed to determine feasibility of shipping any oversized loads to or within Alaska. The limitations are based on different types of equipment, how loads are configured, routing options and timing of the loads. During weight restrictions there are severe limitations on transporting overweight shipments. Anything larger than 40 feet in length and up to 14 feet wide weighing 35-50 tons should be planned well in advance so that limitations can be identified and mitigated.
