Rare Single-Rib, Inclined-Arch Structure Rises In Ohio
A rare type of arch bridge is rising in Columbus, Ohio, as a vital part of the city’s revitalization effort. The generic name of the new Main Street Bridge belies the fact that its single rib-tied arch design, tilting 10° from the roadway, is the first ever in the U.S.
In July, general contractor Kokosing Construction Co., Fredericktown, Ohio, placed the fifth and final 63-ft-long arch segment of the 660-ft-long crossing over the Scioto River in a 140,000-lb pick, says Kokosing area manager Tom Graf. The other four steel arch segments were spliced together and placed in 500,000-lb picks.
