This bridge is a 1/4 of a mile long bridge across the Black River near the confluence with the Mississippi River.
At this location, the Black River can get wide. This would explain the length of this bridge and the nearby BNSF bridge.
Built in 1928, the bridge features a pair of 6-panel, riveted Warren Through Trusses. In addition to the 68 spans of wooden trestle on this bridge, there are three 30' deck girders likely relocated from another place, and are likely older than the trusses.
Railroad records confirm that the three girder spans were relocated here in 1913. Identical spans exist along this same line at Bridge #613 and Bridge #614 in Bangor.
Overall, the bridge appears to be in good condition. This structure replaced another truss bridge, built in 1886 and possibly relocated to western South Dakota upon replacement.
The author has ranked this bridge as being moderately significant, due to the truss design.
