This through truss lies hidden behind the ghost town of Gregory's Landing.
Commonly known as the Gregory Bridge, it crosses the Fox River at the point where it flows into the Mississippi River.
The bridge features a large, 7 Panel Pratt Through Truss with pinned connections. It is approached by a single through girder span, and an I-Beam span on the south. The north end contains a short I-Beam span as well. These spans are of skewed construction, particularly on the south end.
These three spans were added in 1934 in response to a public outcry over the railroad causing significant flooding issues. This would later be resolved in 1939 in the case of Jones V. The Chicago, Burlington & Quincy Railroad.
The bridge is set on concrete substructures. It appears to be in fairly good condition, although it is often obscured from public view.
Gregory's Landing is little more than a ghost town. Years of flooding forced residents out of the town, and the remaining homes are summer vacation homes set on the Mississippi River.
The author has ranked this bridge as being moderately significant, due to the common design, and significant alterations. Despite this, the bridge retains a decent amount of historic integrity.
