This unique bridge sits on the west end of Fall Creek, near a park at Fall Creek Millpond.
It can vaguely be seen from US-12, although not well. That is how the author found this bridge, and it came as a complete surprise.
The bridge consists of two parts. The 90' Pony truss is the more significant part. It consists of heavy diagonals, and heavy riveting.
Considering the reported date is 1898 for this span, it is certainly far heavier than expected for the time period. This also would've been one of the first built up pony trusses designed for railroad use.
The heavy connections would certainly suggest a later build date, although Lassig was known for exceptional modern and groundbreaking engineering.
The deck girder span is much more basic, although it has some extra support on the west end. This could possibly make this unique bridge a candidate for replacement.

The bridge has been ranked as moderately significant due to the innovative design seen in the pony truss. In addition, the expansion is an alteration that could be considered historic itself.
