PORTLAND, Maine — U.S. Sen. Susan Collins of Maine continues pushing the government to lift federal weight limits on trucks traveling on much of Interstate 95.

Collins is asking senators to approve a one-year pilot project exempting Maine’s highways from the 80,000 pound federal truck limit.

Collins wants to allow trucks weighing up to 100,000 pounds on Maine’s interstate highways. Currently, trucks weighing 100,000 pounds are allowed to travel on Interstate 95 from the New Hampshire border to Augusta, where the limit drops to 80,000 pounds. Heavier trucks then head to smaller, secondary roads.

Collins says keeping the heavy trucks on the highway is safer and would prevent wear and tear on the smaller roads.
