The driver whose vehicle damaged the historic Dearborn High Bridge is being issued a citation.
Drew Allen of Great Falls is being cited for driving a vehicle that was too heavy for the bridge. Allen was driving what is believed to be a 35-ton tractor trailer over the bridge that was only rated for a 7-ton load.
The bridge was temporarily shuttered but later reopened. Total costs for repairs have not been determined.
The unique, 251-foot bridge crosses the North Fork of the Dearborn River in a canyon about 15 miles southwest of Augusta on Highway 434. The county accepted a bid of $9,000 from King Bridge Company of Cleveland, Ohio, for construction in 1897.
The Department of Transportation completed a $1 million rehabilitation of the bridge in 2003.
