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

Franklin County

Named for Benjamin Franklin, Franklin County was created from Whitman County in 1883. The county is located in south-central Washington at the convergence of the Snake and Columbia Rivers.

Railroads were key to the county's development as towns grew up around railroad stations.  Irrigation improvements after the completion of Grand Coulee Dam further improved the economic infrastructure and helped support the development of ranching and farming.

Pasco is the county's seat and largest city.  Pasco, Richland and Kennewick are collectively known as the Tri-Cities and have close economic ties. The area boomed during World War II years, when Hanford Nuclear Reservation brought a large number of workers into the region.

Today, Franklin County's economy continues to have a strong agriculture and food-manufacturing base. Public and private educational and healthcare services are also important employers, adding to the region's economic diversity.  

Franklin County's population has grown steadily and in recent years Franklin County became the first Hispanic-majority county in the Pacific Northwest. It is also one of the region's fastest growing counties.
