Located in the Grand Boulevard neighborhood of Chicago, this bridge crosses South Dearborn Street at W. 40th Street.
Built in 1905 as the Chicago Junction Railway raised their tracks through the area, the bridge consists of a single through plate girder span, set onto concrete substructures. While the bridge was originally built for three tracks, only two tracks remain.
In addition, the bridge consists of a ballasted deck. This deck has protected the bridge since construction, leading to lower than normal amounts of section loss. The bridge has been abandoned for many years, although it has not been removed.
This type of bridge is typical for early grade separations in Chicago.
Overall, the bridge appears to be in fair to good condition, primarily due to the ballasted deck. It is unknown who currently owns the bridge.
The author has ranked this bridge as being locally significant, due to the common design.
