DDZ Bridge over New Fork River

The DDZ Bridge over New Fork River is a Kingpost pony truss bridge located near Boulder, Wyoming, which carries Sublette County Road 136 across the New Fork River. The bridge was built in 1917 by Lincoln County's government, as Sublette County had not yet been formed. Unlike most truss bridges at the time, the bridge was built with timber trusses rather than steel; it is the only wooden two-span Kingpost truss bridge remaining in Wyoming. The bridge's construction is considered to be "the most sophisticated" of extant wooden truss bridges in the state.[2]
