High Steel Bridge

High Steel Bridge is a truss arch bridge that spans the south fork of the Skokomish River in Mason County, Washington. It was built in 1929 by Simpson Logging Company as part of a logging railroad. Its construction opened up an area of Olympic Peninsula timber that was previously inaccessible. The bridge span supported a single logging railroad track. In 1950, the tracks were replaced with wooden planks, allowing vehicles to pass. 1964 brought the relatively modern addition of concrete decking and guardrails. The High Steel Bridge is one of only two Washington bridges that is considered a long-span structure formerly used as part of a logging railroad.
