Located south of Massey, this large pony truss and girder bridge crosses Tete des Morts Creek along the Mississippi River. The bridge is actually closer to Gordon's Ferry, although it is listed with Massey, due to the location in Dubuque County.
The bridge is located at the mouth of the creek, where it becomes very wide. It was accessed by asking permission. Encyclopedia Dubuque has a great article on the history of this creeks name.
Built in approximately 1901, the bridge consists of a single 6-panel pin connected Pony Truss. In addition, a pair of through girder spans approach the truss on the south end. The entire bridge sits on concrete substructures.
Like many bridges along this route, this structure was also built in 1901. It appears that major upgrades occurred during 1901, with the installation of several truss bridges throughout this line.
The main truss span is a standard design. Milwaukee Road oftentimes used these, due to the durability. The girders are also of standard design, featuring curved ends. An unidentified plaque once existed on the girder spans as well.
Currently, the bridge is owned by Dakota, Minnesota & Eastern.
Overall, the bridge appears to be in good condition, with little major deterioration. However, many bridges along this route have been replaced in recent years.

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