In 1887, the Parsons & Pacific Railroad (P&P) constructed 31 miles of new railroad, extending between Parsons, Kansas and Coffeyville, Kansas. The following year, an additional five miles would be constructed to Dewey, Oklahoma. The railroad was acquired by the Kansas & Pacific Railroad in 1887, which was merged into the Missouri-Kansas-Texas Railway (MKT) in 1899. The MKT had acquired and constructed a sizable system in Texas, Oklahoma, Missouri and Kansas. In Between 1901 and 1904, the Missouri, Kansas & Oklahoma Railroad (MK&O) constructed an additional 349 miles between Dewey and Oklahoma City, Oklahoma. The MK&O was consolidated into the MKT in 1904. This route became one of the major mainlines for the MKT, connecting industries throughout Oklahoma and southern Kansas. Flooding damaged bridges along the route in 1973, and the entire route would be abandoned.
Located in Coffeyville, this through girder bridge once carried the MKT over 12th Street. Built in 1910, the bridge consists of a single 90-foot through plate girder span, set on concrete abutments that were constructed the same year. The bridge is located immediately west of the Santa Fe bridge, and is one of four through girder bridges located in the area. The girder was fabricated by the Wisconsin Bridge & Iron Company, which fabricated dozens of bridges for the MKT. This design of bridge was commonly used by railroads throughout the United States, as it was durable and easy to construct. While a majority of the line was abandoned in the 1970s, it appears that this bridge was still in use until the 1990s. The bridge is now closed to all traffic, and its future uncertain. It is believed that the bridge continues to be owned by Union Pacific Railroad, the successor to the MKT. Overall, the bridge appears to be in fair condition, with some deterioration to the concrete noted. The author has ranked this bridge as being locally significant, due to the common design.
