Rock Point Arch Bridge, Spanning Rogue River & Old Pacific Highway, Route 271, Gold Hill, Jackson County, OR

Significance: The Rock Point Arch Bridge was the first reinforced-concrete bridge that Conde B. McCullough designed for the Oregon State Highway Department after he became the State Bridge Engineer in the spring of 1919. Topography of the construction site prevented the use of traditional trestle-type falsework. Instead a Howe-truss bridge supported form work for the ribs of the main arch.
