Spanning the Rogue River in the county of Curry, Oregon is the Isaac Lee Patterson Bridge. Also known in names like the Rogue River Bridge and the Isaac Lee Patterson Memorial Bridge, this structure is actually a historic one, proven by the fact that it is designated by the American Society of Civil Engineers as a National Historic Civil Engineering Landmark in 1982.

Built in 1932, the Isaac Lee Patterson Bridge was designed by the well-known bridge engineer Conde McCullough. It got its name after the former Oregon Governor, Isaac Lee Patterson who held office from 1926 to 1930.

The Isaac Lee Patterson Bridge still bore some of McCullough?s defining elements, which are the concrete arches, but it was an example of the designer?s daringness with using a new method of construction known as the Freyssinet method.
