Bridge of Pines, Ermatinger Drive in Irvine Park, Chippewa Falls, Chippewa County, WI

Significance: In 1906, the city of Chippewa Falls established Irvine Park. The Bridge of Pines represents two phases of the park's development, In 1907 the Wisconsin Bridge and Iron Company erected a one-span arched Warren truss across Duncan Creek near the park's main entrance. In 1913, the Worden-Allen Company incorporated this bridge into a three-span structure crossing a ravine in a north addition. Both companies were prominent bridge-building firms that continued into the 1970s-1980s. The 146-foot structure incorporates the continuous top chord, a design apparently unique to these two companies. The Bridge of Pines is possibly the only remaining metal truss in Wisconsin specifically designed as an ornamental park bridge.
