Deschutes River Bridge
Description
The bridge over the mouth of the Deschutes River is an early example of a long bridge constructed by the Oregon State Highway Department (OSHD) under the guidance of bridge engineer Conde B. McCullough.
The bridge was constructed along the Columbia River Highway shortly after McCullough assumed the position of state bridge engineer and is a rare example of an early steel plate girder bridge constructed by the OSHD. At this time the OSHD was developing a reputation for concrete construction, especially concrete arch bridges.
Even with an elegant balustrade rail, the bridge features little in the typical detailing know on the more iconic Conde McCullough structures. This is likely due to the fact that the structure was already in design when McCullough assumed the bridge engineer position.
The bridge was replaced in 1955 as a result of The Dalles Dam construction which raised the water level in the area approximately 30-feet.
