Although much of the Chicago L could be described as one long bridge, and even though the approaching L from the north indeed is also a Warren deck truss, this span over Congress Parkway stands out as unique and independent of the design of the other sections of L. The Congress Parkway span contains two truss lines that have members far more massive than the truss spans north of the road, which also are composed of four truss lines. The differing design is because the span over the Congress Parkway is longer than most of the spans of the railway.
