History & significance

Bridge L4005, constructed by the Joliet Bridge and Iron Company in 1905, is a riveted/bolted steel Pratt pony truss with half-hip configuration. The bridge carries pedestrian traffic on Township Road 124 over Riceford Creek in Houston County. It has been significantly altered presumably due to deterioration concerns regarding the steel truss members. The bridge features new concrete abutments and truss stringers. Bridge L4005 is significant as the earliest and longest surviving half-hip Pratt pony truss built by the Joliet Bridge and Iron Company in Minnesota. Despite alterations to the superstructure and substructure, Bridge L4005 remains significant as an example of a half-hip Pratt truss.
