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

Columbia County

Columbia County was carved out of Walla Walla County in 1875. It is 31st in size among Washington's 39 counties. Located in southeastern Washington, the county is dominated by agricultural land largely specialized in wheat, asparagus and pea farming. Agriculture and food processing are dominant along with food manufacturing. Ranching, logging and local government are also important to the county's economic base.  Dayton, the largest town, is also the county seat.

Recent economic expansions have included new wind projects and work to reestablish food processing with the Blue Mountain Station project.

Ski Bluewood, a local ski facility, is an important source of tourism and seasonal employment for residents across the region.
