Located in the Portage Park neighborhood of Chicago, this concrete slab bridge crosses West Wilson Avenue near Cicero Avenue and the Kennedy Expressway.
Built in approximately 1926, the bridge features four concrete slab spans, set onto concrete substructures. The bridge follows a common 1920s design, using minimal decorations.
As one of the last ordered track elevations in Chicago, this bridge and the others in the area feature concrete instead of steel designs seen further south.
Overall, the bridge appears to be in fair condition, with minimal significant deterioration. However, there is a fair amount of spalling on the piers.
The author has ranked this bridge as being minimally significant, due to the common design and large numbers of similar bridges in the area.
The photo above is an overview.
