The ENP Bridge over Green River is a historic bridge located near Daniel, Wyoming, which carries Sublette County Road CN23-145 across the Green River. The Western Bridge and Construction Company built the bridge circa 1905. The bridge has two spans, both Pratt trusses; the longer span is a Pratt through truss, while the shorter is a Pratt pony truss. The use of both through and pony trusses in the same bridge was uncommon in Wyoming, and the bridge is the only surviving example of a Pratt truss bridge in this style. Read more on Wikipedia
