Main Street Bridge Replacement
First of it’s kind to be built in the U.S.
INSIDE THE PROJECT
Located in Columbus, Ohio, this inclined, single-rib arch bridge is the first of its kind to be built in the U.S. The $44 million, ODOT bridge replacement project is a three-span structure measuring 675 feet in length – with a main span of 400 feet. The bridge’s foundation consists of 30 each, 70 foot long-6 foot diameter shafts reinforced with double-cage rebar. The cast-in-place concrete substructure includes internal cooling pipes to maintain rigorous temperature tolerances. Each pier has more than 325,000 pounds of reinforced steel and features single, 900 cubic yard concrete pours. The superstructure of the 5.75 million pound bridge consists of trapezoidal steel vehicular boxes with floor beams projecting from both sides that support the cast-in-place concrete deck.
The structure’s focal point is a fabricated steel arch that spans the bridge’s main channel and supports the pedestrian walkway. Peaking at 60 feet above the deck, the arch is connected by rigid steel struts and cables. Exterior aesthetics also include a bikeway and scenic overlook. Roadway and utility work were also included on the approaches to the bridge.
