The Interstate Highway System
American roads until the 1950s were mostly narrow highways running through every town along the way. Urban routes were repeatedly driven through Black neighbourhoods, often the very ones marked on the redlining maps, and tore them apart; resistance to this gave rise to the modern movement for community consultation in planning. The network moved freight from rail to road and made car dependence structural rather than chosen. It is also why American energy use per head diverges so sharply from European.
