Smoother roads could be ahead for truckers in Maine. A plan to ease up on highway weight limits moved forward, again, today in Congress. House lawmakers gave the okay to a transportation bill that includes a one-year pilot project to lift those federal limits. Senator Susan Collins has pushed hard for the project.The Senate is now expected to vote on the bill with the weight limits project this weekend or the first of next week. Then it goes on to the President for his signature.
