Scenarios about 'American transportation'

American transportation encompasses the development and evolution of mobility systems across the United States, from colonial-era roads and canals to modern highways, railways, and air travel networks. Its history reflects the nation's territorial expansion, industrialization, and economic growth, with innovations like the transcontinental railroad, interstate highway system, and commercial aviation reshaping settlement patterns and national unity. In alternate history scenarios, different transportation priorities or technologies could fundamentally alter American development, military capabilities, and cultural cohesion.
