In 1882, the Wisconsin Central Railway (WC) constructed a short branch from Neenah, Wisconsin to Menasha, Wisconsin.  The WC was reorganized as the Wisconsin Central Railroad (WC) in 1888.  Between 1895 and 1896, the Milwaukee and Lake Winnebago Railroad (M&LW) constructed a 27 mile line between Hilbert Junction, Wisconsin and Manitowoc, Wisconsin.  To reach the WC line at Neenah, the railroad utilized trackage rights over the Chicago, Milwaukee & St. Paul Railway (Milwaukee Road).  The M&LW and the WC were sold to a reorganized Wisconsin Central Railway (WC) in 1899.  This line provided the WC with a connection to Lake Michigan, and the WC served numerous industries in Manitowoc.  In addition, the WC operated three separate car ferries, which connected to eastern railroads in Michigan.  In 1909, the WC would be leased by the Minneapolis, St. Paul & Sault Ste. Marie Railway (Soo Line), which itself was controlled by the Canadian Pacific Railway (CP).

The Soo Line had constructed a large network of railroads, connecting the Upper Midwest with Canadian Railroads.  Throughout the early 20th Century, this line remained a secondary line for the Soo Line, which served several large industries, as well as the car ferries.  In 1961, the WC would be merged with other CP subsidiaries Duluth, South Shore & Atlantic Railroad and the Soo Line to form Soo Line Railroad, a company controlled by CP.  In the late 20th Century, the car ferry operations were discontinued, reducing the importance of this line.  In 1984, the Soo Line would be reorganized as the Soo Line Corporation in advance of a pending purchase of the Chicago, Milwaukee, St. Paul & Pacific Railroad (Milwaukee Road).  In 1987, this line would be sold to Wisconsin Central, Ltd. (WC).  Known as the "new" Wisconsin Central, the railroad acquired several excess rail lines from the Soo Line, Milwaukee Road and Chicago & North Western Railway.  In 2001, WC was merged into Canadian National Railway (CN), becoming the American subsidiary of CN. A short segment in Manitowoc was abandoned and removed in the mid-2000s.  Today, CN continues to operate this line as the Manitowoc Subdivision, which connects other CN lines near Manitowoc to the rest of the CN system.


Located near the south end of Little Lake Butte Des Morts, this steel stringer bridge carries the former Soo Line Manitowoc Branch over the Neenah Channel of the Fox River. The first bridges at this location consisted of timber pile trestles, which were continuously renewed in the late 19th and early 20th Centuries. In the early 20th Century, a parallel spur track was constructed immediately east of this bridge, joining the mainline at the north end. In late 1939, the spur track bridge was reportedly reconstructed with a new steel stringer structure, and it is believed that the main bridge was reconstructed at the same time. Currently, the bridge consists of 19 27-foot steel stringer spans, set onto concrete abutments and steel cylinder piers. Due to the alignment of the railroad, the bridge runs at a heavy 6.5-degree curve, with several of the spans being skewed to account for the curve. The superstructure uses a standard design, with four shallow beams per span and no exterior rivets. The piers are constructed using an oval shape steel cylinder, which has been filled with concrete. An unknown contractor fabricated the superstructure, and an additional unknown contractor constructed the substructures. Steel stringer spans were commonly used by railroads, as they were durable and easy to construct. Steel cylinder piers were popular for long bridges in this area, as they could easily be constructed under live traffic without requiring cofferdams or dredging. Many bridges in the Fox Cities area use a similar design to this bridge, due to the dynamic nature of the Fox River and need for lengthy, permanent structures with no concern for clearance underneath. Since the initial construction, the bridge has seen no significant alterations. The spur track was removed later in the 20th Century, and today the bridge remains in regular use. Overall, the bridge appears to be in fair to good condition, with no significant deterioration noted. The author has ranked this bridge as being locally significant, due to the common design and unknown history.
