Route 66

Route 66 is representative of the early development (circa 1920’s) of cross-country highway routes in the United States. Creation of Route 66 was the collection of many individual efforts at the state, county and local level that established what eventually became a continuous numbered highway from Chicago, Illinois to Santa Monica, California. Notable civil engineering features and achievements occurred at many locations along the Route 66 alignment during its development.

Route 66 is historically significant for its effect on regional and national economic, social and political development
