The Purdy Bridge is a continuous reinforced concrete box girder bridge that spans 550 feet (170 m), with a central span of 190 feet (58 m), between Henderson Bay and Burley Lagoon. The bridge connects Purdy, Washington with the Purdy Sand Spit Park and Wauna, Washington.
Purdy Bridge was completed on September 29, 1937,[2] at a cost of $62,000, from a design by Homer M. Hadley. It was the first bridge in the United States to utilize a reinforced-concrete box girder design and it was the longest continuous box girder bridge in the United States at the time.[3][4]
The bridge was added to the National Register of Historic Places in 1982.
