The stunning Rock Creek Bridge, located in southeastern Pittsburgh County, Oklahoma, is listed on the National Register of Historic Places. Carrying ‘N 409 Rd.’ across Rock Creek, the structure lies approximately 9 miles SSE of Blanco, and just west of the Indian Nation Turnpike. It was constructed during 1937 with federal Works Progress Administration (W.P.A.) labor.

The curving structure is nearly 200 feet long, utilizes native stone in its design, and bears two shield plaques in which are inscribed “WPA 1937”.

NRHP: “The design of the bridge and the materials used in its construction are characteristic of WPA bridge projects in the area. The design of the bridge exhibits a considerable degree of technical skill in using a  curve to surmount the obstacle of carrying the road over the creek bed and around the foot of a mountain. The entire bridge is  curved, but the south ninety-two foot approach, constructed of stone walls containing fill used to elevate the roadbed, is  more sharply curved to the east as it  carries the road around the foot of Hewitt Mountain. This unusually long approach constructed of stone, as well as the bridge’s stone piers and abutments, display craftsmanship that is  characteristic of WPA construction.”
