The Powell Bridge, located on Conway Ridge Road (off Hwy E) over Big Sugar Creek 0.4 miles west of Powell, McDonald County, Missouri, is significant in the area of engineering. The Powell Bridge was constructed in 1914-1915 and officially accepted on Monday, August 16, 1915. It is an iron 8-panel, pin-connected Pratt through truss with a 4-panel, pin-connected Pratt pony truss approach span. It is the only remaining nineteenth-century pinned-connected Pratt through truss bridge in McDonald County. The bridge is especially noteworthy because it is still intact today and being used for vehicular traffic 95 years after it was opened. Today it does have a load limit specification. The significance of this bridge is based on a well-preserved long-span example of a mainstay structural type. It is also one of the few roadway bridges in Missouri that combine a Pratt through truss and a pony truss span.
