Located near the former station of Perryville, this large truss bridge crosses the Kishwaukee River.
Built in 1904, these two 6-panel pin connected Pratt Through Trusses were built to replace an older truss bridge of unknown type. They are constructed of standard design, and sit on stone and concrete substructures.
Trusses like these can be found on this route in particular. The style of portal bracing was an IC standard.
Today, the bridge has remained rather unchanged. Canadian National upgraded the bridge floor by replacing the bottom bracing. This change does not significantly affect the historical integrity of the bridge, and it also will allow for a much longer service life.
The bridge can be accessed on either side from surrounding park land. Foot trails from the end of Barley Ridge Trail get to the northwest of the bridge, while the trails in Deer Run Park cross underneath the east end.
Overall, the bridge appears to be in good condition. Recent rehabilitation should assure for a lengthened service life.

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