This is a short pin-connected pony truss. During the 2012 HistoricBridges.org visit, the bridge was found to have a new deck including new steel deck stringers. Also, supplemental rods were bolted to the vertical members. The work looked very recent in 2012, and the timber was dated 2010-2011.
The supplemental rods added to the bridge did not extensively alter the bridge, since the original vertical members remain in place alongside the rods. The alteration is also reversible, which means it could be removed at a later date. The only irreversible aspect of these rods is that holes were drilled in the cover plate. The supplemental rods added to the bridge would have been an inexpensive way to avoid demolition and replacement and increase the service life of the bridge. However this type of repair did not improve the condition of any of the original bridge material. If additional money becomes available, Morrow County could rehabilitate the bridge by repairing the original bridge material. This bridge could likely be rehabilitated to like-new condition for much less than it would cost to demolish and replace the bridge.

Summary of Significance
The date of construction of the ca. 1890 pin connected Pratt pony truss bridge is not documented in Morrow County records, but stylistically it represents the standardization of design typical of ca. 1890 and
later bridges. It is one of 20 examples of the important bridge type in Morrow County with the oldest extant example dating to 1874. Many are undocumented and represent the era of standardization. Morrow County retains many
deteriorating pin connected truss bridges largely because of the economic issues associated with there replacement in a largely rural county with no industrial tax base. This example is not historically or technologically
