In 1880, the Milwaukee, Lake Shore & Western Railway (MLS&W) constructed a 24 mile branch line from the newly constructed mainline at Eland, Wisconsin to Wausau, Wisconsin. A short spur was extended northwards in Wausau between 1881 and 1883, crossing the Barker-Stewart Island. In 1892, an additional 40 miles would be constructed from Wausau to Marshfield, Wisconsin. This line served as a branch line for the MLS&W, serving industries in the Milwaukee area and connecting to other railroads at Marshfield. The MLS&W had constructed a modest network of railroads through northern and eastern Wisconsin, primarily serving industrial interests. Due to the success of the MLS&W, the railroad was purchased by the Chicago & North Western Railway in 1893 (C&NW). The C&NW had acquired and constructed a vast network of railroad lines throughout the Midwest during the late 19th Century, and the MLS&W system provided more opportunities for expansion.
During the early 20th Century, the C&NW sought to improve operations by constructing new lines and improving existing lines. The C&NW had become one of the premiere Midwest railroads, and sought to stay profitable and competitive. The Manitowoc, Green Bay and North Western Railway (MGB&NW) was incorporated as a subsidiary of the C&NW in 1904, and constructed 61 miles between Duck Creek Junction, Wisconsin and Eland in 1906 and 1907. The MGB&NW was formally merged into the C&NW in 1909. Upon completion of the new line, this line served as a connection between several C&NW lines through eastern and central Wisconsin. Throughout the 20th Century, this line remained a secondary line for the C&NW.
By the late 20th Century, the C&NW sought to consolidate operations and abandon or sell unprofitable lines. In 1981, the line between Wausau and Marshfield was abandoned. In 1994, the segment between Duck Creek and Weston, Wisconsin would be abandoned, and the remainder of the trackage in the Wausau area sold to Wisconsin Central, Ltd. (WC). WC had purchased a large amount of former Soo Line and Milwaukee Road trackage in central and eastern Wisconsin in 1987, primarily to continue serving industries in the area. As part of the 1994 abandonment, the line between Duck Creek and Weston was purchased by the Wisconsin Department of Natural Resources for use as a trail. In 2001, WC was purchased by Canadian National Railway (CN), and became the American subsidiary of the railroad. In 2021, the Wausau area trackage was sold to the Fox Valley & Lake Superior Rail System (FOXY). Today, FOXY operates trackage in Wausau, including a spur through Barker-Stewart Island. The segment between Duck Creek and Weston is now part of the Mountain-Bay State Trail.
Located in Howard, this through plate girder bridge carries the former Chicago & North Western Railway mainline over an out of service Escanaba & Lake Superior Railroad line (former Chicago, Milwaukee, St. Paul & Pacific Railroad mainline). The first bridge at this location likely consisted of a timber pile trestle bridge, with a longer timber stringer center span. The C&NW initially constructed temporary wooden pile trestle bridges at locations along this line, which allowed the approach embankments to settle without damaging a permanent structure. By the early 1910s, the C&NW determined that the embankments had adequately settled, and replaced the original structure with the present through plate girder span in 1914. Currently, the bridge consists of an 80-foot skewed single track through plate girder span, set onto concrete abutments. The superstructure uses a standard design, with heavy girders, a traditionally composed floor and rounded and tapered girder ends. Similar to other spans from the era, the floor is composed of four equally spaced I-beam stringers and I-beam floorbeams. The substructures also use a standard design, with sloped wing walls. American Bridge Company fabricated the superstructure, while the Cleary-White Construction Company constructed the abutments. Through plate girder spans were commonly used by railroads, as they were durable and easy to construct. Since the initial construction, the bridge has seen no significant alterations. Today, the bridge is used as part of the Mountain-Bay State Trail, and a wooden deck and wooden handrails have been added to the structure. 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.
