Utah officials say thieves have pulled off the largest single copper-wire heist in the state Department of Transportation's history.
The Salt Lake Tribune reports up to 35,000 feet of wire were taken from light poles along a mile-long stretch of Interstate 15 in Salt Lake City.
Transportation Department spokesman John Gleason says the theft was discovered last week and would cost about $50,000 to repair.
Officials say it's a bit of a mystery how the thieves carried out the crime because the area is so busy. Gleason says it likely took them several hours or days, and they probably had to use a vehicle to pull the heavy wire out from the ground.
He says the thieves may have dressed as construction workers so they wouldn't look suspicious.
