Like many other bridges in Chicago, this bridge, as well as its neighbors are simple steel stringer bridges, resting on steel bents.
However, unlike many other bridges in Chicago, this bridge has the outer faces encased, which once contained many decorative tiles.
Built in 1912, the bridge consists of six steel stringer spans, set onto concrete and steel substructures.
The bridge once crossed US-66, a major road to the American Southwest.
In addition, the bridge also borders the CN Bridge and the CSX Bridge.
However, the bridge has seen a significant alteration by local advertisements and paint, which cover up the original architectural details.
The bridge once carried a maximum of 4 tracks and is currently not in use. It is not known if the bridge will ever be used again.
Overall, the bridge appears to be in good condition, recently receiving a coat of paint.
The photo above is an overview.
