PORTLAND, Maine — The full Senate Appropriations Committee has signed off on a measure that once again would allow heavy trucks to use interstate highways in Maine and Vermont.
The provision approved on Wednesday was placed in the transportation spending bill by Republican Sen. Susan Collins of Maine and Democrat Sen. Patrick Leahy of Vermont.
The proposal now goes to the full Senate. There’s no similar language in the House version.
Trucks weighing between 80,000 and 100,000 pounds are forbidden from using the interstates and must use secondary roads in Maine and Vermont.
Collins says putting the heavy trucks on interstates instead of secondary roads would make highways safer. But some highway groups oppose the measure.
