The unincorporated community of Kiona is just south of concurrent highways Interstate 82 (I-82) / U.S. Route 12 (US 12), where SR 225 terminates.

[5] The bridge, as well as the remainder of SR 225 are considered a major collector road by the Washington State Department of Transportation (WSDOT),[6] which the Federal Highway Administration defines as linking towns to larger arterials.

[7] Every year, WSDOT conducts a series of surveys on its highways in the state to measure traffic volume.

[13] The first proposals for the current bridge were submitted in November 1955, with a cost estimate of $140 thousand (equivalent to $1.2 million in 2023).

[14] The bridge was designed so that there was a clearance of 2 feet 9 inches (0.84 m) higher than the 1933 Yakima River flood level.

[2] Everett McKellar of Chelan won the contract to build the bridge, designed by Homer M. Hadley in 1956.
