This through truss was originally conjoined with the northern bridge at this location.
Built in 1902, the bridge features a pair of 8-panel riveted Warren Through Trusses. Following a standardized design, this truss span is identical to several others along the Great Northern system.
In addition to the trusses, a single through girder span also approaches the bridge to the north. A timber approach once connected the through girder span to the northern bridge. However, this trestle was filled and replaced by modular concrete spans in 2009, effectively forming two bridges.
At the time of construction, this bridge crossed a southern channel of the Minnesota River. This channel has gradually become the main channel, and the northern channel has dried up.
Overall, the bridge appears to be in good condition. Recent upgrades have likely lengthened this bridges life for more years to come.

The author has ranked this bridge as being moderately significant, due to the truss design.
