In 1881, the Chippewa Falls and Northern Railway began construction on a 14 mile route between Chippewa Falls and Bloomer, Wisconsin.
The following year, the route would be extended 55 miles to a point known as Chicago Junction, near Spooner.
Concurrently, the Chicago, St. Paul, Minneapolis & Omaha was working on 61 miles of track between Superior, Wisconsin and Spooner.
By 1883, the Eau Claire & Chippewa Falls Railway began construction on a 10 mile route between the namesake cities. When completed, the route would become part of the Chicago, St. Paul, Minneapolis & Omaha Railway, which was controlled by the Chicago & North Western Railway.
By the end of 1883, the EC&CF would become part of the Omaha Road.

The Omaha Road remained independent in operations until 1957, when it was formally leased. In 1972, it was fully merged into the Chicago & North Western.
A majority of operations were ended on this route in the 1980s and 1990s. In 1995, the C&N.w was purchased by Union Pacific Railroad.
Today, a segment from near Gordon to Superior is operated by Canadian National, while the segment from Trego to Spooner is the Wisconsin Great Northern.
The route between Gordon and Cameron is now the Wild Rivers Trail, while the southern end between Cameron and Eau Claire is owned by Union Pacific, but leased by Progressive Rail owned Wisconsin Northern.

The bridge here is one of the most scenic across the Namekagon River. It consists of deck girder spans and trestle approaches.
The two main spans across the river replaced a single 150 foot deck truss in the 1960s. This loss did affect the historical aspect of this bridge significantly, as the truss span dated to 1892.
However, the bridge did retain some historical value with the road span, which dates to 1926.
The substructures are a mix of wood, concrete and steel. Advanced corrosion has eaten through portions of the pier between the highway span and river span.
Overall, the bridge remains in fair to poor condition. Corrosion is widespread on the structure.

The author ranks this bridge as being locally significant, due to the replacement of the truss.
