Main Street Bridge

Columbus, Ohio

DLZ was chosen by the City of Columbus to conduct conceptual, preliminary, and final design of a replacement for the existing Main Street Bridge over the Scioto River in Downtown Columbus. The City wanted a distinctive bridge and  the 660-foot bridge features a single rib arch designed with a unique 10 degree incline. It is the world’s first inclined arch bridge tied with cables and struts while incorporating separate pedestrian and vehicular decks.

Columbus prides itself on an elegant and integrated infrastructure. With neighboring arch bridges and an art deco heritage of arches throughout the city, leaders considered clean, classical lines an important design element of the new bridge. It needed to embody the architectural character of the Civic Center Historic District while providing motorists and pedestrians with an unobstructed view of the water and skyline.

The replacement bridge features three vehicle lanes (two eastbound and one westbound), a 5-ft sidewalk on the south side, a steel box girder roadway, piers that complement the superstructure design, and a concrete pedestrian deck on the north side that sweeps horizontally and vertically away from the roadway to provide an unobstructed view of the City’s downtown. Everything in the bridge design is asymmetrical, with the road deck designed using cantilevered floor beams which support the pedestrian walkway.
