The Main Street Bridge in Columbus, Ohio is a 700 ft, three-span, inclined tied 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.

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.
