Located in the town of Oregon, this large through truss bridge crosses the Rock River.
While the piers are dated 1892, the superstructure of this bridge was replaced in 1904. The bridge consists of two large 6-panel pin connected and riveted Pratt Through Trusses. These trusses are replaced by a pair of deck girders on either side.
It is likely that the 1892 bridge consisted of four trusses. It is unknown if these trusses were used elsewhere, but does seem like a definite possibility.
The combination of pin connected lower connections and riveted upper connections is rather unique. While it is oftentimes seen on CB&Q trusses, most railroads did not use this design.
Overall, the bridge appears to be in fair to good condition, with little significant deterioration noted.
