In January of 1891, the Kansas City, Fort Smith & Southern Railroad began construction of a 45 mile segment of line from Grandview, Missouri to the Marais des Cygnes River at Amoret, Missouri.
Later in 1891, another 12 miles to Hume, Missouri would be opened. Another 99 miles would be opened to Joplin, Missouri by 1893. The line would continue south from this location the next year.
The new route left Grandview and headed straight south, along the Kansas/Missouri border. It would be acquired by the Kansas City, Pittsburg and Gulf Railroad in 1893.

The route connected into Kansas City via a portion of the Kansas City Suburban Belt Railway that was constructed in 1877. The Kansas City & Independence Air Line would complete the connection in 1892.

In 1900, the Kansas City Southern Railway would be born through the combination of several companies, including those above.
The KCS was a well funded and constructed railroad, with track extending from Kansas City to the Gulf of Mexico. The line was heavily rebuilt in the first decade of the 20th century.

One of the major issues for the railroad was between Leeds (now part of Kansas City) and Grandview. The railroad followed the Blue River in a deep gorge, which oftentimes meant large grades and floods.
To counter this, the Kansas City and Grandview Railway was formed in 1923. Controlled by the KCS, the road sought to rebuild the mainline track between Leeds (now Kansas City) and Grandview.

Upon completion in 1929, the line was a success. Featuring massive bridges and deep cuts, the route proved to be an operational dream.
The line also helped the KCS economically, and improved their outlook during the Great Depression.

The KCS has had little changes since 1929. After the opening of the new track and route, the old line was sold to the St. Louis-San Francisco Railway (Frisco). Frisco and successor Burlington Northern operated the line until the construction of the interstates through the area.
In 2017, the Kansas City-Joplin line is the mainline of the KCS, providing connections to the south and the east. It continues to see a steady traffic base.

View an article regarding the construction of this realignment.

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.
