The Columbus Dispatch examined each of the 35 bridges over the Ohio River connecting Ohio to neighboring Kentucky and West Virginia. Reporter Randy Ludlow discovered that seven are rated as structurally deficient. That group includes three of the four bridges owned by the Ohio Department of Transportation. The investigation revealed that highway officials have plans to close one bridge when the temperature drops to 5 below zero. The steel of the old bridge becomes so brittle in bitter cold that engineers fear it could fracture, raising the possibility of the span toppling.
