The exterior spans, Spans 1 and 4, are 41’-0” long, and the interior spans, Spans 2 and 3, are 72’-4” long. The structure has an overall length of 226’-8” (centerline-to-centerline bearing) and an overall width of 94’. The bridge carries 2 northbound and 2 southbound traffic lanes over I-294 in addition to one ramp lane in each direction.
