COLUMBUS — Capital City Group has been awarded the crane rental and willl be providing a Manitowoc 2250 III (300-ton Crawler Crane) to pick individual pieces of steel weighing up to 465,000 pounds. The bridge will be an iconic structure, and is intended to contribute to the revitalization of the city by linking parks and communities in Franklinton, the oldest part of the city, with the downtown core on the east side of the Scioto River. An inclined single-rib tied arch bridge - believed to be the first of its kind in the United States, and one of only a few in the world - will carry vehicle and pedestrian traffic and is intended to revolutionize the skyline.

The structure has three vehicle lanes to accommodate eastbound traffic across the Scioto River, a 2m-wide pedestrian walkway on the south side of the bridge, and a 6m-wide pedestrian deck that sweeps horizontally and vertically away from the road to provide an unobstructed view of the city.

The bridge has a steel box girder roadway and a concrete pedestrian path, and was designed with piers that complement the superstructure design. The simple, yet sculptural, design that emerged starts as a single, unified section from both ends, gradually rising as it separates into three lanes for vehicle traffic and a fourth lane for bicycle and pedestrian traffic.

The bridge's overall length is approximately 202m, which consists of three spans; a main span of 122m and two side spans of 40m each. Meanwhile, the three-lane vehicular deck is 10.7m wide, and the pedestrian walkway is 5.5m wide, providing an area from which people can view the skyline to the north. The pedestrian bridge is about 9m from the roadway, connected by cables that tie from the floor to the L-struts that support the structure, and 1.2m above it.

The Main Street Bridge is believed to be the first example of an inclined arch tied together with cables and struts; it will also be the world's first single inclined arch bridge that incorporates both pedestrian and vehicular decks. It is slated to open in June 2009.
