Significance: The South Hamma Hamma River Bridge is one of two identical bridges spanning the north and south branches of the Hamma Hamma River (the other is the North Hamma Hamma River Bridge, HAER No. WA-97). They are part of the main highway along the east side of the Olympic Peninsula. Each is a three-hinged reinforced-concrete through arch. In many of their details, they are similar to other early reinforced-concrete through arches built by the Washington State Highway Department. Both Hamma Hamma River bridges are on the National Register of Historic Places.
