The US Interstate Highway System
Federal highway investment expanded mobility while displacing communities and reshaping cities.
The Federal-Aid Highway Act of 1956 funded a national interstate system in the United States. The roads supported long-distance travel, trucking, suburban growth, and military logistics, while construction also displaced households and divided urban neighborhoods.
Highways changed commerce and access, but their effects were not uniformly positive. Route placement often reinforced racial and economic inequalities, and car dependence shaped housing, pollution, and public transit investment.
Without the system, rail, local roads, or other transport might have received greater investment, but those alternatives would not necessarily have connected the country as efficiently. Supply chains would have evolved differently rather than simply being strangled.
Infrastructure is a physical expression of priorities that can last for generations. Evaluating a road network requires asking who gained access, who was displaced, and what other forms of mobility were made harder.

When I value faster travel, whose neighborhood, health, or alternatives might be paying for it?
