The Sibley Bridge Company was chartered in 1888 to construct the large bridge across the Missouri River at Sibley. Similarly, the Mississippi River Railroad & Toll Bridge Company constructed the bridge across the Mississippi River.
The entire line became part of the Atchison, Topeka & Santa Fe Railway in 1900. This mainline would see heavy reconstruction throughout the first decade of the 20th century. Reconstruction included tasks such as relocation and double tracking.
The line was critical to the development of the State of Missouri. The line provided the quickest and most direct route between the agricultural center at Kansas City and Chicago.
Throughout the 20th Century, the line remained one of the most critical rail lines in the United States. The heavy duty mainline saw guards during World War II, due to the critical connection between Southern California and Chicago.
Despite the importance of the line, the ATSF would see serious financial issues in the late 20th century. Because of this, they merged with rival Burlington Northern to form BNSF Railway. BNSF currently operates the line as the Marceline Subdivision; and it is a part of the greater Southern Transcon Line; completed in 1908.
The line connects to the equally as important Chillicothe Subdivision on the east, and the Emporia Subdivision on the west.
This simple girder bridge crosses County Road 221 and a small stream near Bosworth.
While the eastbound span was originally built in 1903 and has a deck girder design, the westbound span would be added in 1910 and utilizes a through girder design. The substructures on this bridge are made of both concrete and stone.
This design is common along the Santa Fe mainline between Chicago and Kansas City.
Overall, the bridge remains in good condition.
The author has ranked this bridge as being locally significant, due to the common design.
