West of Quenemo, a massive Pratt Through Truss bridge once crossed the Marias des Cygnes River.
The previous truss bridge here was built in 1905 to replace a single track, and evidently shorter through truss. This old truss may have been relocated to another location.
Interestingly enough, the truss bridge was damaged by floodwaters soon after completion. However, the piers were strengthened and the bridge was in service within a couple days.
The main truss was a massive 7-panel, pin connected Pratt Through Truss. It was approached by a concrete beam span and I-Beam spans on both ends.
These concrete beams replaced an older 1905 deck girders at an unknown date, possibly approximately 2000.
Interestingly enough, the approaches were rebuilt in 1945. The I-Beam spans that rest on timber substructures were added at this time.
The other substructures of the bridge were mostly made of concrete, except for one small part of the east pier; which had been built of stone. This is evidence of an older bridge.
Unfortunately, this bridge was replaced during 2018 and 2019. A new through girder bridge was opened in 2019. The truss bridge was marketed to anyone who wanted it, but it unfortunately came with a heavy cost to simply remove from the site.

Despite the great historic integrity this structure demonstrates, the author has ranked it as moderately significant, due to the more common nature of this type of truss in the region.
The photo above is an overview. Fortunately, this bridge is easy to access; sitting parallel to Maple Street.
