Located at the intersection of West Kinzie Street and N. Clinton Street in the Near West Side neighborhood, this large viaduct crosses W. Kinzie Street.
Built in 1910 as the C&NW built a new station, the bridge consists of two separate faces. Because the bridge is located on a curve, it consists of a complex set of deck plate girder spans, set onto steel towers and concrete abutments. The west face consists of seven such spans, and is curved outwards and skewed to accommodate the Geneva Subdivision. The east face consists of twelve spans, and has a large through girder span.
The east face also is considerably more complex, because a Union Pacific spur runs underneath the east track before turning east near the south end of the bridge.
It is also unknown if the bridge was originally designed as presently seen, or if it had a protective facade on it. The bridge is listed as a concrete encased beam on railroad documents.
The bridge also consists of a ballasted deck. As one of the largest rail junctions in Chicago lies north of this bridge, the bridge is six tracks wide, and all are in use.
Overall, the bridge appears to be in fair to poor condition. Some deterioration of metal components on this bridge was noted, although October 2018 street views show repair efforts on the bridge.
The author has ranked the bridge as being locally significant, due to the common design.
