The Benton City – Kiona Bridge is a steel box girder and cable-stayed bridge carrying two lanes of Washington State Route 225 over the Yakima River in Benton City, Benton County, Washington. The current span was opened to traffic on July 4, 1957 and measures 400-foot-long (121.9 m) by 26-foot (7.8 m) wide. Two bridges had previously connected the cities of Benton City and Kiona before and were located 300 feet (91 m) downstream. The first bridge was open by 1901, and the immediate predecessor bridge was closed and torn down in 1964. The bridge is owned and maintained by the Washington State Department of Transportation, and was added to the Washington Heritage Register on January 25, 2002.
The Benton City – Kiona Bridge is located about 150 feet (46 m) from the southern terminus of Washington State Route 225 (SR 225) in Benton City, just south of downtown. 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. The bridge is 400-foot-long (121.9 m) by 26-foot (7.8 m) wide, carrying two lanes of SR 225, linking Benton City to I-82/US 12. While SR 225 on both sides of the bridge features bicycle lanes, the bridge does not. The bridge does feature 4-foot-wide (1.2 m) sidewalks raised 10 inches (25 cm) above the roadway surface.
The bridge, as well as the remainder of SR 225 are considered a major collector road by the Washington State Department of Transportation (WSDOT), which the Federal Highway Administration defines as linking towns to larger arterials. Every year, WSDOT conducts a series of surveys on its highways in the state to measure traffic volume. This is expressed in terms of average annual daily traffic (AADT), a measure of traffic volume for any average day of the year. In 2012, WSDOT calculated that 9,500 vehicles traveled on SR-225 along the bridge.
