PRIME provided engineering design for the substructure of this new 562-foot-long precast post-tensioned rib arch signature replacement bridge across the Scioto River in downtown Columbus, Ohio. Due to extensive deterioration of the bridge, the City of Columbus replaced the existing 7-span earth-filled concrete spandrel arch with a 5-span structure consisting of 3 post-tensioned cast-in-place concrete plate arch girders on reinforced concrete piers and abutments. The three middle spans are full arches and the end spans are half arches, landing high at the abutments to accommodate a river walk along both the banks. The abutments are founded on steel “H” piles, and the piers are founded on drilled shafts socketed into the limestone bedrock.

PRIME prepared the design and plans for the substructure and roadway approaches to the bridge. The substructure components of the bridge essentially consist of the two abutments, two sets of curved plaza walls at each abutment, and four piers. PRIME designed and detailed these elements. The plaza walls were designed as counterfort walls in order to optimize the wall section due to its freestanding height. The contract plans were prepared in accordance with ODOT requirements. In addition, PRIME also conducted the subsurface investigation program for the proposed bridge.
