In late June, as the Pennsylvania legislature debated whether or not to raise the wholesale gas tax, PennDOT Secretary Barry Schoch warned that he would likely have to place weight restrictions on bridges across the state in order to extend their useful life if additional funding was not allocated. Some may have thought this was just a bargaining point, but now 1,000 bridges across the state have been posted with reduced weight limits.
Congress set the current 80,000-pound weight limit for trucks on Interstate highways in 1991. For years proponents of raising the limit have argued that it would reduce the number of trucks on the road, shipping costs, and congestion. On the other side of the argument are those who believe these benefits are outweighed by the fact that heavier trucks are more difficult to control and stop, and that heavier trucks cause greater damage to roads and bridges.
