Purdy Bridge
The Purdy Bridge is a continuous hollow-box girder bridge that spans between Henderson Bay, Washington and Burley Lagoon, connecting Purdy, Washington with the Purdy Sand Spit Park and Wauna, Washington. It was built on September 29, 1937, and at the time was the longest continuous box girder bridge in the US, at a cost of $62,000 from a design by Homer M. Hadley. At the time it was built, Purdy Bridge was the first bridge in the United States to utilize a reinforced-concrete box girder design.
The bridge was added to the National Register of Historic Places in 1982.
