Encyclopedia
State Route 225 is an 11.32 miles (18.2 km) long two-lane state highway
located entirely in Benton County
, Washington, United States. The highway travels over the Benton City – Kiona Bridge
, which is listed on the Washington Heritage Register and National Register of Historic Places
, over the Yakima River
. After turning through Benton City
, the highway parallels the river for the remainder of the route. Several different proposals have been introduced to alleviate traffic flow issues at the SR 224
/ SR 225 interchange.
just north of the Interstate 82
/ U.S. Route 12
interchange in south Benton City
. The highway passes over the Yakima River
on the Benton City – Kiona Bridge
, which is listed on the Washington Heritage Register and the National Register of Historic Places
. After a brief turn to the west, the highway resumes northerly into Benton City, serving as the main street through town. The Yakima River continues to parallel the highway as it exits town, passing between a hill on the west side and the river, followed by Horn Rapids County Park on the east until the highways terminus at SR 240
.
Every year the Washington State Department of Transportation
(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), which is a measure of traffic volume for any average day of the year. In 2009, WSDOT calculated that as few as 1,000 cars used the highway at the terminus at SR 240, and as many as 7,800 cars at the interchange with SR 224.
WSDOT is studying several different proposed changes to the SR 224 / SR 225 interchange to improve traffic flow, including signalizing
the intersection, moving the off ramp from I-84 and making a 5-way stop, and multiple different roundabout
solutions, which are the WSDOT preferred methods of improving the intersection. Costs are estimated to be between $2,000,000 and $7,400,000.

History
SR 225 was added to the highway logs during the 1991 legislative session, and since then the only major changes to the highway have been the replacement of the bridge over a drainage canal about 0.27 mile (0.4345218 km) from the western terminus of the highway.WSDOT is studying several different proposed changes to the SR 224 / SR 225 interchange to improve traffic flow, including signalizing
