¹The permissible loads are computed to the nearest 500 pounds as required by statute.

²The following loaded vehicles must not operate over H15-44 bridges: 3-S2 (5-axle) with wheelbase less than 38 feet; 2-S1-2 (5-axle) with wheelbase less than 45 feet; 3-3 (6-axle) with wheelbase less than 45 feet; and 7-, 8- and 9-axle vehicles regardless of wheelbase.
