Origin of 'superhighway'
The word 'superhighway' emerged in the mid-20th century, reflecting the rapid development of highway infrastructure following World War II. In the United States, the 1956 Federal-Aid Highway Act marked a significant milestone in this evolution, leading to the creation of an extensive network of highways designed for high-speed vehicle traffic. The term combines the prefix 'super-', meaning 'above' or 'beyond', suggesting a roadway that surpasses ordinary highways in design and function. Over the years, the concept of superhighways has expanded globally, with countries around the world constructing similar roadways to support increased automobile travel and economic growth. This evolution in roadways has had profound impacts on urban planning, suburban expansion, and the overall landscape of transportation.
