Yuma in Yuma County, Arizona — The American Mountains (Southwest)
Ocean-to-Ocean Highway Bridge
Constructed - 1915 & Rededicated - 2002
Government engineers designed the bridge in Washington without knowledge of the site. Because the engineers were unfamiliar with the unpredictable Colorado River, problems arose early in the construction. While beautiful in design, the structure required falsework across the river for support during construction. Sudden, violent flooding was common on the river at the time and washed out the falsework twice. The contractor finally erected the truss on the south side of the river and floated it into position on barges.
In 1979, the bridge was listed on the National Register of Historic Places. It was an important link in the Transcontinental Highway and is an early and rare example of its structural type in Arizona.
Erected 2002 by Arizona Department of Transportation, Federal Highway Administration, City of Yuma, Yuma County, Quechan Indian Tribe, Arizona State Parks, Bureau of Indian Affairs, Cannon & Associates, Inc. Ashton
