County Transportation Metrics is a project of the Washington State Association of Counties (WSAC) and will provide a roadmap for setting transportation priorities.

Benton County

Named after Missouri Senator Thomas Hart Benton, Benton County was created in 1905. The county is located in southeastern Washington at the confluence of the Columbia, Snake and Yakima rivers.  The county seat is in Prosser and its largest city is Kennewick.

Ranching and dryland farming have played important roles in the area's development. Today nuclear-related and other research and development investments are key to the economy. The Hanford Project developed the plutonium used in the first nuclear bomb. Continued federal investment has led to scientific diversification and nuclear and chemical clean up. In the late 1980's Washington State University expanded into the area, offering advanced degrees.

In recent years recreational and tourism attractions are developing along with the popularity of the regional wine industry.
