Located in the village of Lake Forest, this through girder bridge is the western of two bridges at the intersection of Deerpath Road and US-41 (Skokie Highway).
Built in 1936 as a grade separation for a major transportation corridor, the bridge features a single through girder span with a concrete fascia. Unlike the parallel bridge which features an actual rigid frame, this bridge only mimics one.
In addition, the bridge consists of a ballasted deck and concrete substructures.
This type of design is common for grade separations in the 1930s. Many were constructed as part of major New Deal Era projects, especially along new highways.
Little changes have been made to this bridge since construction. Overall, the bridge appears to be in good condition, with only minor substructure deterioration noted.
The author has ranked this bridge as being minimally significant, due to the common design and newer age.
