CTH D Bridge, Spanning Eau Galle River, Eau Galle, Dunn County, WI

Significance: The CTH D Bridge is a single-span, Parker through truss designed by the State Highway Commission and erected in 1934-1935 by the Worden-Allen Company of Milwaukee, Wisconsin. Although not identified as a significant structure in Cultural Resource Management in Wisconsin (the state's cultural resource management plan), the bridge is one of approximately thirty-five Parker trusses identified by the state's Historic Bridge Advisory Committee in the early 1980s. Fewer than twenty of these bridges remain today. As well, Cultural Resource Management identifies the Worden-Allen Company as a prolific bridge builder in the state. With its integrity largely intact, the CTH D Bridge is significant as a good and increasingly rare example of a Parker truss that was built by a prominent Wisconsin bridge-building company.
