Stillwater Road Bridge, Spanning Woonasquatucket River at Stillwater Road, Smithfield, Providence County, RI
Summary
Significance: The Stillwater Road Bridge No. 949 is an excellent example of a nineteenth century lenticular wrought-iron truss bridge. The lenticular truss was a patented design built exclusively by the Berlin Iron Bridge Company of East Berlin, Connecticut. Of the more than half dozen Berlin Iron Bridge Company bridges erected in Rhode Island only two are extant. This is the only surviving lenticular highway truss; the other lenticular truss bridge is the Interlaken Mill Bridge (c.1885) in the Town of Coventry. The Stillwater Road Bridge exhibits such early characteristics as patented truss configuration, pinned connections and light and narrow proportions. Original intact features include the trusses and floor system. The bridge was determined eligible for listing on the National Register of Historic Places on January 10, 1989.
