Crooked River High Bridge, Steel arch bridge in Terrebonne, Oregon

The Crooked River High Bridge is a two-hinged steel arch bridge with a truss-stiffened spandrel, carrying a 7.3 m concrete roadway. Its main arch spans 100.6 m, supplemented by reinforced concrete beam approaches of 29.3 m on the east and 11.6 m on the west. The total length is 141.4 m and the deck sits 90 m above the canyon floor.

Construction began in August 1925 under Portland contractors Kuckenberg and Wittman, following site surveys from spring 1924, and the bridge opened to traffic in September 1926. It was officially dedicated on 15 July 1927. It carried US 97 until the four-lane Rex T. Barber Veterans Memorial Bridge opened upstream in 2000, after which the old span was kept for pedestrians.

The bridge is used today for bungee jumping above the 100-metre canyon, and pedestrians share the crossing with visitors heading to the viewpoints of Peter Skene Ogden State Park. Three bridges span the gorge here: the 1911 Crooked River Railroad Bridge downstream, McCullough's 1926 arch, and the 2000 Rex T. Barber Veterans Memorial Bridge upstream.

The bridge is easy to access and well-maintained for pedestrians of all abilities. Comfortable footwear is recommended, and be mindful of wind conditions that are common at this elevation.

The bridge has become a destination for commercial bungee jumping, attracting thrill-seekers who leap from its height. This use has transformed the crossing into a hub for adventure tourism in the region.
