This is a beautiful example of the rainbow arch structure type. The technical name is a concrete through arch bridge. They are a very attractive bridge design, and among the most impressive and rare of concrete bridge types. This is a good example of the structure type, having retained historic integrity, with no railing or floor beam modifications.
As of 2013, this bridge has been closed to traffic and has an uncertain future. While it has been found eligible for listing in the National Register of Historic Places and has High Significance according to the Historic Bridge Inventory, Wood County is not exactly noted for preserving historic bridges, although its not to late (yet) for them to change this reputation.
The bridge does suffer from severe deterioration in certain areas including spalling and extensive map cracking with efflorescence found on the floor beams and deck. The arch, hangers and railings are all in much better condition. A possible preservation scenario would be to replace the deck and floor beams completely, while repairing the arches.
Information and Findings From Ohio's Historic Bridge Inventory
The bridge carries a 2 lane road over a stream in a sparsely developed, rural setting.
The 1 span, 95'-long, rainbow (thru) arch bridge has flat-paneled arch ribs with floorbeam hangers and articulated floorbeams. Concrete balustrades fill between the hangers, and flat-panel parapets extend between the arch ribs and the wingwalls.
Some loss of fabric from spalling.
Summary of Significance
The rainbow arch bridge built in 1930 is a complete, albeit later, example of a bridge type that was in use from the late 1900s to 1930s. The inventory has identified seven surviving examples dating from 1909 to
1930 (Phase 1A Update, 2008). This one, like several others, appears to be the state bridge bureau's design that was in use during the 1920s to early 1930s based on the details.
The bridge is one of 5 remaining examples of the type that was once not uncommon in Ohio. It offered an aesthetic treatment preferred in urban and picturesque settings. The 6 examples date from 1909 to 1930, and each is of high significance given their limited numbers and importance within the context as the aesthetic alternative to the thru truss bridge.
