Main Street Bridge (Columbus)

The Main Street Bridge in Columbus, Ohio is a , three-span, inclined arch suspension bridge over the Scioto River. The bridge is the first in North America and the fifth in the world to use an inclined single-rib-tied arch superstructure.〔(【引用サイトリンク】 title=Main Street Bridge )〕 The final cost for the bridge was $60.1 million.
==History==

The original Main Street bridge was a multiple-span, art-deco open-spandrel concrete deck arch bridge, built in 1937. After years of degradation due to weather and traffic, the bridge was deemed unfit for use and closed in 2002.〔
Wanting an iconic structure to replace the old bridge, the city of Columbus contracted Dr. Spiro Pollalis, professor of design technology and management at the Harvard University Graduate School of Design to design the bridge. His design, altered slightly for budget reasons, opened for traffic on July 30, 2010.〔
When the former bridge closed, engineers estimated that a replacement would cost approximately $19.5 million. However by 2004, estimates climbed $29.5 million. When planners received construction bids in 2006, the lowest was $44.1 million. Cost overruns, design changes and inspections added another $10 million to the structure's final cost.
