Abstract: The Columbus Gateway Arch Bridge is an innovative twin ribbed steel arch structure with a post-tensioned composite concrete deck, transverse post-tensioned composite steel box girders and cable-stayed hangers that will serve as a dramatic entrance into Columbus, Ind. Construction is scheduled to begin this spring on the estimated $4 million four-lane bridge, which crosses State Route 46 on Interstate 65, replacing an existing steel girder bridge of standard DOT design. Besides meeting aesthetic requirements, the structural design had to respond to a variety of constraints, including a limited structure depth, concerns over feasibility of a planned battered pile foundation and the need for phased construction to maintain four lanes of traffic at all times on I-65, a major vehicle and trucking route, and two lanes on SR 46. The project featured extensive use of three dimensional finite element analysis.
