Truss bridges that are as small as this two panel bridge are very rare on today's roads. Likely, they are rare because a bridge this small does not cost a lot to replace, so a lot of examples have been lost. They would not have been built long into the 20th Century either, when steel stringers would have become efficient to roll at these lengths, making a steel stringer bridge a more preferable option for short spans. This bridge remains with good historic integrity. It is a good representative example of small-scale truss bridge construction. It is also presumed to be the construction of the Lafayette Bridge Company, a noteworthy in-state bridge builder.
HistoricBridges.org photo-documented this bridge in its original location. Later, in 2011, the bridge was preserved and relocated to the antique tractor area of the Jackson County fairgrounds. The main map page for this bridge reflects the current location of the bridge. To see the former, original location of the bridge click here.

Statement of Significance
Pinned Warren ponies represent an early stage in the truss' development. This bridge is otherwise of standard design and retains its original members, including latticed guardrails. The northwest endpost has an I-beam brace welded to it.
Concrete abutments and wingwalls support the single-span Warren pony truss. The pinned structure extends 35'9" in two panels. Its interior vertical is manufactured from two pairs of laced angles and its diagonals from a pair of angles. The I floor beam is U-bolted to the vertical below the lower chord and carries the concrete deck with its 15'9" roadway.
Very likely a 36-foot by 16-foot bridge, on stone
abutments, constructed over Wayman Ditch by the Lafayette Bridge Company
for $221.00; the contract was let on 9 June 1896. [county research
