Located in the Logan Square area of Chicago, this bridge crosses West Webster Avenue between Ashland and Elston Avenues.
Built in 1916 to replace an older bridge, the bridge features a four spans of deck girder, set onto stone, concrete and steel substructures. The bridge was originally built for four tracks, although the outer tracks are now unused.
As of late 2018, the bridge was being rehabilitated, along with the Deering Bridge.
Overall, the bridge appears to be in fair condition, with some deterioration.
The author has ranked this bridge as being locally significant, due to the common design and large numbers of similar bridges in the area.
