Description 

No specific reference to the North Omaha Creek Bridge was found in county records, but based on its truss leg bedstead configuration, it was probably built about 1905. Although numerous truss leg bedstead bridges were erected throughout the state, most featured industry-standard floor systems with longitudinal stringers. This bridge has transverse I-beam stringers that rest on a continuous angle section and are bolted and riveted to the webs of deeper longitudinal I-beam stringers. Its transverse joist floor system distinguishes it as a peculiar - and somewhat structurally redundant - hybrid of truss and beam construction. The bridge, located near Winnebago, is thus technologically significant as an uncommon exercise in bridge engineering in Nebraska. [From NebraskaHistory.org]

I too noted that some elements of this span were not necessarily conducive to the WIBCo. normality. Standard might have went a little "throwback" with some of their earlier contracts...I have certainly seen other firms do this in their infancy.

This is one of the most unusual bridges I have seen. Note the unusual bottom chord design. The Nomination Form associates the Standard Bridge Company with building the bridge, but apparently the date of construction is not certain, since ca. 1905 was used. Standard Bridge Co. was formed in 1900:

I agree the bridge looks like a pre-1900 bridge, but the bridge details such as the bottom chord and the design of the end post casting is unusual vs other Wrought Iron Bridge Company bridges. The use of threaded rod with nut connection details is not unique to Wrought Iron Bridge Company.

This may be a freak bridge that does not conform to the dates that we would expect them to. Like the bowstrings in Wisconsin:

The cast endpost connectors suggest a structure that is much older than the 1905 date given. It is more likely a Wrought Iron Bridge Co. span from about 1880.
