The bridge was built in 1934 by West Coast Construction Company as one of five reinforced concrete arch structures constructed in Washington during that era. It was listed on the National Register of Historic Places in 1982 for its engineering significance.

The bridge stands as a testament to early 20th-century engineering practices, earning its place on the National Register of Historic Places in 1982.

The bridge carries traffic on U.S. Route 101 and is accessible as part of normal vehicle passage through the area. You can pull off the road nearby to get a closer look at the structure and appreciate its design.

The bridge features three lateral struts that distribute both traffic and wind loads across the entire span in an innovative way. This engineering detail was an advanced solution for maintaining structural stability under diverse conditions.
