Description 

The Little Sheep Creek Bridge in remote Wallowa County is a representative example of a typical small stream crossing designed by the Oregon State Highway Department during the 1930’s. The bridge was constructed in 1935 and was designed by the highway department under the guidance of notable state bridge engineer Conde B. McCullough. The bridge is 23-foot long single span reinforced concrete tee-beam structure located on the Imnaha Highway between the town of Joseph and the small community of Imnaha.

The Little Sheep Creek Bridge is an excellent example of the detailing utilized by the highway department engineers during this era. The railing is a variation of the baluster railing utilized on some of the large signature coastal bridges built during the same time. The bridge illustrates the states commitment at this time to lasting structures that accent their place in the environment. Despite the remote location of the structure the small bridge still is adorned with the details that one would find on a large scale structure in more urbanized areas.
