Okay, so KHRI has a very similar bridge, on Hobbs Road, which has been demolished. I may have been confused when making previous comments.

Saline County used to have a very large collection of small pony trusses, many of which would have been wrought iron. Unfortunately, the Flood of 2007 obliterated nearly all of them.

This bridge is one of the few survivors of that devastating flood. It is also a rare example of a Missouri Valley Bridge and Iron Works structure. (I believe that the company became the Missouri Valley Bridge and Iron Co. in 1888 - will post a KSHS link about this).

This one should be considered to be of high historic significance, especially if those outriggers are cruciform members.

The KSHS images reveals that this bridge has outriggers which might possibly be cruciform. I cannot tell for sure. This is potentially a highly significant bridge.

This bridge may be getting replaced soon through the use of local funds. It is almost certainly older than the Kansas default date of ca. 1910. I will change the date to ca. 1890.
