The Isaac Lee Patterson Bridge, also known as the Rogue River Bridge and the Isaac Lee Patterson Memorial Bridge, is a concrete arch bridge that spans the Rogue River in Curry County, Oregon. The bridge carries U.S. Route 101 across the river, near the point where the river empties into the Pacific Ocean, and connects the towns of Gold Beach and Wedderburn.
A bridge with strong Art Deco influences, the Isaac Lee Patterson Bridge is a prominent example of the designs of the Oregon bridge designer and highway engineer Conde McCullough. It was designated a National Historic Civil Engineering Landmark by the American Society of Civil Engineers in 1982.
McCullough employed a new method of concrete arch construction named the Freyssinet method, named after the French bridge engineer Eugene Freyssinet. This method uses precompressed arches which pemitted the use of smaller arch ribs, thereby reducing the weight and cost of the bridge. McCullough's design was the first usage of this technique in the United States.
