BOISE -- Idaho senators aim to raise an additional $57 million per year to build and repair Idaho roads -- largely from truckers from out-of-state.

It's part of the push to ease a $200 million shortfall in transporation funding.

Senators Tim Corder, a Mountain Home Republican who owns a trucking company, and Shawn Keough, from Sandpoint, introduced the bill Wednesday to charge all trucks that weigh more than 60,000 pounds a $660 annual registration fee.

The truck owners would then pay 4.5 cents for every mile they travel on Idaho roads.

The current system, Corder says, lets out-of-state truckers drive Idaho roads without paying the full cost.

The Idaho Trucking Association, which represents long-haul truckers, will likely oppose the measure, he said.
