This massive lift bridge is the only vertical lift bridge over the Chicago River, with each tower standing 195 feet above the river.
While the bridge was started in 1913, it would not be completed until 1915. This bridge replaced a swing bridge built in 1883, and consists of a 10-panel Pratt Through Truss with riveted connections and a skew of 47 degrees. The bridge rests on concrete substructures.
When first built, the bridge was considered to be the most massive lift bridge in existence. The bridge has seen little change since then, only losing the title of heaviest lift bridge.
The bridge was designed to be able to raise the grade 25 feet further up, as well as possibly be able to support an additional bridge.
In addition, the bridge was designated a City of Chicago Landmark in 2007. Overall, the bridge appears to be in good condition, with no significant deterioration noted.

The author has ranked the bridge as being regionally significant, due to the large scale design.
