Hanford Site
The roots of public transportation in the Tri-Cities region can be traced back to the beginnings of the Hanford Site, which was opened in 1943 in the midst of World War II, and ultimately produced the plutonium used in the Fat Man bomb that was detonated over Nagasaki, Japan. General Electric, and later the Atomic Energy Commission, provided bus service as a way to bring its workers to and from the Hanford site to locales in the area, largely Richland.
