Conde B. McCullough was the head of the Bridge Division of the Oregon Department of Transportation from 1920-1935. In that position, he was personally responsible for the design and construction of 162 of the most beautiful and functional bridges in the United States. Virtually all of the bridges that make up the Oregon Coast Highway 101 (formally known as the Roosevelt Military Highway) are McCullough designs. The highway was just beginning to be paved in 1927 and had no permanent crossings of the numerous rivers that line the Oregon coast. By 1932, the highway was paved, but it wasn't until 1936 when the three final bridges were completed over Coos Bay, Alsea Bay and Yaquina Bay that the highway was complete.
