CPKC MO-13 Bridge

In 1882, the Chicago, Milwaukee & St. Paul Railway (Milwaukee Road) began construction on a new railroad line, extending from Cedar Rapids, Iowa to Ottumwa, Iowa.  The 40-mile line would be completed in 1884.  By 1885, work was authorized to begin towards Kansas City, Missouri; a critical railroad hub in the Midwest.  The extension opened in 1887, giving the Milwaukee Road a direct route between Chicago and Kansas City.  The Milwaukee Road acquired and constructed a large amount of track throughout the Midwest during the 1870s and 1880s.   At the Cedar Rapids suburb of Marion, the route connected to the Milwaukee Road mainline across Iowa.  By the early 1900s, a direct connection to the Mississippi River town of Davenport was desired, and in 1901, the Rutledge Cutoff was completed.  The cutoff extended from Rutledge, Iowa to Muscatine, Iowa, and allowed for a quicker way to access the Milwaukee Road facilities at Davenport, as well as shortened the travel time and distance from Chicago to Kansas City.  Between Davenport and Muscatine, the railroad jointly owned a line with the Chicago, Rock Island & Pacific Railroad (Rock Island).

The Milwaukee Road operated this route as a principal mainline, and the line served as a primary connection between the two largest railroad hubs in the United States. The Milwaukee Road was often in financial trouble, especially after the costly Pacific Extension was completed in 1909. In 1925, the company declared bankruptcy, and reorganized as the Chicago, Milwaukee, St. Paul and Pacific Railroad in 1928.  Significant upgrades were made to the line in the 1930s and 1940s, although the line remained single tracked.  In 1930-1931, the Milwaukee Road and Rock Island reconstructed their lines from Polo, Missouri to Kansas City, abandoning much of the original line.  A new bridge into Kansas City was completed in 1945, further improving operations.  In 1980, the Rock Island went bankrupt, and the Milwaukee Road purchased the Davenport to Washington, Iowa line; abandoning their own line between Washington and Muscatine.  By 1985, a suitor for the Milwaukee Road was being sought, and the Soo Line Railroad, controlled by Canadian Pacific Railway (CP) purchased the Milwaukee Road in 1986.  In 1997, CP sold this line to I&M Rail Link, which later sold it to Iowa, Chicago & Eastern Railroad (IC&E), a subsidiary of Dakota, Minnesota & Eastern Railroad (DM&E).  In 2008, DM&E and IC&E were purchased by CP.  CP merged with Kansas City  Southern Railway in 2023 to form CPKC, the current owner of this route.  The CPKC operates the Ottumwa Subdivision between Davenport and Ottumwa, the Laredo Subdivision between Ottumwa and Laredo, Missouri; as well as the Kansas City  Subdivision between Laredo and Kansas City.  The route between Polo and Kansas City is shared with Union Pacific Railroad, which eventually acquired the former Rock Island line.  This route now forms the principal mainline of the CPKC system, and traffic is expected to increase significantly over the coming years.
