Like many other bridges in Chicago, this bridge, as well as its neighbors are simple steel stringer bridges, resting on steel bents.
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 CSX Bridge and the UP Bridge.
Because the bridge is the middle of the three, it has not been covered up by paint or advertisements.
The bridge once carried a maximum of nine tracks, although five are still in use.
Overall, the bridge appears to be in good condition.
