Idaho Springs Mayor Chuck Harmon knows traffic backups and crashes are common on Interstate 70 through the Colorado mountains. “There is hardly ever a week or a month that goes by that our police or our emergency response folks do not have a serious accident call,” Harmon said. “If we were to stand in this single location for probably just even an hour or two, we would hear squealing tires.” New technology aims to help with that. On Tuesday, the Colorado Department of Transportation will turn on 26 variable speed limit signs on a 10-mile stretch of eastbound I-70 between Georgetown and Idaho Springs.
