The Saskatchewan Ministry of Highways and Infrastructure has established allowable weights for all highways within the province. Maximum gross vehicle weight is dependant on highway classification, maximum registered gross vehicle weight for vehicles, tire size and axle spacing. In order to maximize the economic movement of goods and minimize the damage to road structures, Saskatchewan Highways and Infrastructure assigns special weights to some of our highways. In some cases certain highways are assigned higher allowable weights and in other cases, weights are reduced.
