By moving the expansion joints off the main, cable-stayed span and creating innovative cable connections and tower configurations, Parsons Brinckerhoff Quade & Douglas Inc. (PB) designed a steel bridge with one of the longest cable-stayed spans in the inland waterway system, and at a lower cost than a concrete alternative. The Owensboro Bridge crosses the Ohio River between Owensboro, Kent., and Rockport, Ind. The unique cable-to-deck and cable-to-tower connections can be accessed without special equipment, making maintenance a snap. By placing the expansion joints at the abutments and at the transition from the concrete superstructure to the steel superstructure, designers left a 3,375 ft. span in the middle with no joints, creating a smooth ride for passengers.
