Located in Dubuque, this is the only crossing of Catfish Creek along this route. Despite this, there are over 20 crossings of the branches of Catfish Creek.
Originally built in 1900, the bridge was rebuilt in 1921. The eastern span of the bridge was original to 1900 and retained in the 1921 reconstruction. The two western spans were added at this time, likely to replace a truss. The bridge sits on concrete substructures.
Spans like this are common for crossing large creeks, as they make exceptionally good multiple span structures. There is a visible difference between the eastern span and the western two spans.
Currently, the bridge is owned by Canadian National. It is located underneath Rockdale Road.
Overall, the bridge appears to be in good condition, with no visible major deterioration.
The author has ranked this bridge as being locally significant, due to common design.
