This wrought iron bowstring truss bridge was relocated to Ohio Village, an open air museum that is part of Ohio History Connection museum. The bridge came from Smith Road over Sycamore Creek in Crawford County, Ohio. It was moved in 1989. It is a classic example of the King Bridge Company's bowstring truss bridge, and includes their ornamental detail at each end of the truss. To walk on this bridge you must visit during operating hours and pay an entry fee. HistoricBridges.org visited this bridge at the end of the day after the museum had closed so only distant overview photos are available.

Information and Findings From Ohio's Historic Bridge Inventory
The bridge carries a pathway over a depression at the Ohio Historical Society in Columbus.
Bridge was near Bucyrus in Crawford Co. on Smith Road over Sycamore Ck. SFN 1741500. Moved to the Ohio Historical Center, Columbus in 1988.
Summary of Significance
The bowstring truss is NR listed (1980). It was relocated to OHS in 1988, but the relocation was sensitive and did not adversely impact the bridge's integrity of design and the technological significance of this rare bridge type/design. From HAER OH-46: "It [is] a prime, existing example of a wrought iron tubular arch design, patented by Zenas King of Cleveland's King Iron Bridge and Manufacturing Company in 1861 and improved upon in 1867. The patenting and manufacturing of the prototype of this design, among the first in the United States for an iron bridge, launched the career of this bridge designer and builder." Bowstring trusses are characterized by arched top chords and a trussed or lattice web. They rank among the rarest and most technologically significant of 19th-century metal truss designs since they appeared early in the evolution of iron bridge development and were almost always based on the patents or proprietary designs of bridge builders and engineers. The progenitor of the form was the famed engineer Squire Whipple of New York, who built the first example in 1840 over the Erie Canal at Utica. After the Civil War, Ohio was a center for the development of the bowstring with its concentration of metal bridge-building companies. Companies such Wrought Iron Bridge, Champion Bridge, Massillon Bridge, and King Iron Bridge built their reputations on successful bowstring designs with a dizzying number of variant ways of forming and connecting the truss members. The companies emerged in time to fill the burgeoning demand for an economical, prefabricated bridge for use on American roads. Bowstring trusses thus document this exceptionally inventive and technologically significant period in the development of American metal trusses from the 1860s to early 1880s. The ODOT inventory has identified 22 surviving examples dating from ca. 1864 to 1880 (Phase 1A, 2008).
The bridge is one of the 22 extant bowstring truss bridges that survive in the state. Having so many is remarkable, and even though they are "common" based on their numbers, each is an important and irreplaceable record of the development of the metal truss bridge and the ingenuity associated with the Ohio industrial development. The bridge has high significance.
