Dungeness River Bridge, Historic railway bridge in Sequim, Washington, United States

The Dungeness River Bridge is a timber through Howe truss 156 feet long and 22 feet high, with wooden trestles on its east and west approaches. It stands in Railroad Bridge Park near Sequim, Washington, and now carries the Olympic Discovery Trail across the Dungeness River.

The bridge was built in 1916 by the Seattle, Port Angeles and Western Railway and then rebuilt in 1930 with a new wooden structure. This reconstruction established the form that visitors see today.

The bridge is listed on the National Register of Historic Places as one of the last timber Howe through-truss railroad bridges still standing in Washington. Volunteers replaced its planking in 1992 and created a bike trail; the path now links to the Olympic Discovery Trail, a rails-to-trails route.

The bridge carries the Olympic Discovery Trail, a rails-to-trails route, so walkers and cyclists cross on replaced planking between two wooden trestle approaches. The deck was rebuilt after the February 2015 center collapse and reopened in March 2016. The crossing sits inside Railroad Bridge Park, near Sequim.

The bridge's center collapsed in February 2015 after high winds and rainfall; the repaired structure reopened in March 2016. It is one of the last timber Howe through-truss railroad bridges remaining in Washington.
