Lupus Bridge, Spanning Splice Creek at Moniteau County Road 4, Lupus, Moniteau County, MO

Significance: Built one hundred years ago by one of the Midwest's most prolific bridge erectors, the Lupus Bridge features a pin-connected Pratt truss superstructure. From the 1870s through the 1910s, thousands of pinned Pratt trusses were erected on Missouri's roadways. Although several hundred of these structures remain in use today, relatively few date from before the turn of the century. And fewer yet of the 19th century survivors remain structurally intact. The Lupus Bridge stands out among Missouri's pin-connected trusses as an early, well-documented and well-preserved example of what was once a mainstay structural type.
