DDZ Bridge over New Fork River, Historic wooden bridge near Boulder, Wyoming.

The DDZ Bridge carries Sublette County Road 136 over the New Fork River near Boulder, Wyoming. It is a two-span Kingpost pony truss bridge built in 1917 with timber trusses rather than steel, and it is the only wooden two-span Kingpost truss bridge remaining in the state.

This bridge was commissioned in 1917 when the area was still part of Lincoln County, before Sublette County was established. Its construction reflects early 1900s transportation development in rural Wyoming communities.

Locals know the crossing as the DDZ Bridge, and Sublette County Road 136 still uses it. Its timber Kingpost trusses, built in 1917, are the last two-span wooden example of their kind in Wyoming, and the structure was listed on the National Register of Historic Places on February 22, 1985.

The bridge is accessed via Sublette County Road 136 and remains open to vehicle traffic. Visitors should remember this is an active crossing with regular vehicular use.

This is Wyoming's last remaining two-span wooden bridge of its engineering type in the entire state. It displays the sophisticated construction techniques from the early 1900s in its timber design.
