Fidler Bridge, Spanning Iroquis River at County Highway 45, Watseka, Iroquois County, IL
Significance: This two-span bridge, located at an historic crossing over the Iroquois River, includes a 200' through Pennsylvania truss built by the Clinton Bridge and Iron Works, one of two spans in Illinois known to have been built by this Clinton, Iowa builder, and one of three of this type listed in the Illinois Bridge Inventory, the others being at L'Erable, 1903, and Spring Valley, 1934. Pennsylvania trusses were a popular long span bridge type from the late 19th century into the 1930s. Few examples of this truss are known to exist today on American highways, another metal truss type vanishing from the landscape.
