The steel cantilever truss bridge is located just downstream from The Dalles Dam. Although the bridge reaches into the state of Washington, it is maintained by the Oregon Department of Transportation. The average daily traffic on the bridge (US 197) is nearly 8,400. (US 197 connects Washington State Route 14, a few miles to the north of the bridge, with Interstate 84 and US 30, both just south of the bridge, and with U.S. Route 97, about 67 miles [108 km] to the south.)
Ferry service operations began at the site in 1854, but just over a decade later, in 1865, plans for a bridge began. However, it took about another 85 years and the construction of The Dalles Dam before the bridge was finally built. Although the bridge was built in connection with the dam, the bridge opened December 18, 1953, but the dam was not completed until 1957. Due to issues with the dam, the bridge had to be redesigned as a longer one and the location moved slightly farther downstream the originally planned. Notwithstanding, the already fabricated steel components (for the original bridge design) were successfully modified and used in the newly designed bridge. The cost of construction was $2.4 million (equivalent to $72.28 million in 2018).
