The Mott Bridge over the North Umpqua River is located about 40 miles east of Roseburg off of OR-138. The 237-foot structure features a 135-foot three hinged braced spandrel timber arch main span, along with 50-foot approach timber trestles on each approach.
The rustic bridge carries traffic over the North Umpqua River on a 14.5-foot roadway and two 4-foot sidewalks. The bridge links OR-138 to the popular North Umpqua Trail as well as supplies access to the Forest Service and Oregon Department of Transportation maintenance yards on the opposite side to the river.
The timber bridge was built by the Civilian Conservation Corps in 1936, and is the last remaining three hinged timber arch of the three similar structures built in the Pacific Northwest during the Great Depression.
