One of the largest concrete arch structures in the midwestern United States lies in Kansas City, and was constructed in 1928 as a part of a relocation.
This bridge consists of three main arches, with a trio of arches approaching on either end. The bridge sits approximately 80 feet above the base of the ravine it crosses.
The main concrete arch spans are very large open spandrel arches. However, the approach spans are a more simple closed spandrel arch.
Of the three main large bridges, the Blue Parkway Viaduct is identical to this span. These highly decorative yet functional spans were likely built like this due to the public eye.
Another high trestle along this line is located at 63rd Street just south of this location. However, this structure contains deck girder spans, which are considered less visually appealing.

This structure crosses Gregory Boulevard. This secondary street in Kansas City follows a deep valley which eventually leads to the Blue River.
In addition, the bridge crosses a small stream. The bridge is entirely constructed of concrete, and is in very good condition.

The author has ranked this bridge as being moderately significant due to the massive and iconic structure. Several generations have crossed under and over this bridge, making it one of the more iconic structures in the midwest, particularly in the Kansas City region.
