Idaho officials say an extra-long load traveled across U.S. Highway 12 in north-central Idaho to the Montana border late Thursday and early Friday.

Idaho Transportation Department spokesman Adam Rush tells the Lewiston Tribune that the rig carrying a generator skid to an undisclosed destination went from the agency’s weigh station east of Lewiston to the state border in a single night of travel.

Rush says the cargo had been scheduled to move before Christmas but was delayed by weather.

The rig is 163 feet long, weighs about 250,000 pounds, and is 15 feet wide and about 16 feet tall.
