The CKW Bridge over Powder River is a Pratt deck truss bridge near Arvada, Wyoming, which carries US 14/US 16 across the Powder River. The bridge was built from 1932 to 1933 by the W. P. Roscoe Company. The bridge has three continuous main spans and two shallow approach spans. It is the only continuous truss bridge still in use on a Wyoming road and one of only two deck truss bridges built on a major highway. Read more on Wikipedia
