The line became part of the Chicago, Milwaukee & Saint Paul by 1874, which was vastly expanding its empire across the midwest. It had already reached into Iowa and Minnesota, along with extensive networks in Wisconsin and Illinois.
The line was double tracked in the late 1880s and early 1890s, and was part of the Milwaukee to Saint Paul mainline.
The CMStP reorganized into the Chicago, Milwaukee Saint Paul & Pacific in 1912, as it began expanding its empire towards Seattle.
This line saw some of the most stable traffic of the Milwaukee Road, which generated trains day and night.
When the Milwaukee Road fell out of buisness in 1985, it became part of the Soo Line, who eventually dissolved its Wisconsin lines. Most of the Soo Line went to Canadian Pacific, including this line. Canadian Pacific later sold lines off to Wisconsin Central. This line was not included.
Canadian Pacific is the current operator of this line, which sees nearly 110 trains per day, and is the main route from Chicago to Saint Paul with the Amtrack. It is known as the C&M Subdivision.

This bridge is one of the more historic and unique bridges over any road in the area.
The bridge is a total of 320 feet in length, because of a grade difference between Union Pacific's Kenosha Subdivision and the C&M Subdivision.
The long trestle approach on the east end creates a long rise to the higher grade of the C&M subdivision.
The main spans are steel. The piers underneath are concrete, and one is stamped 1910. Unfortunately traffic would not let me across the road.
