Main Street Bridge Replacement

First of it’s kind to be built in the U.S.


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.

The project was the recipient of multiple awards:

  •  AGC Build Ohio Award, 2010
  • National Steel Bridge Alliance, Prize Bridge Award, Major Span, 2012
  • James B. Beechie Design & Preservation, 2012
  • Association for Bridge Design (ABCD), Northeast Ohio Chapter, Outstanding Major Bridge Award, 2012
