Early Cold War and Civil Rights Movement Practice Test

In the 1950s, a major push to boost mobility, commerce, and national defense transformed American infrastructure, led by the creation of the Interstate Highway System. The Federal-Aid Highway Act of 1956 funded an enormous program to build thousands of miles of connected highways across the country. This project reshaped where people lived and worked, spurred suburban growth, and changed the way goods moved, fueling a new era of economic expansion tied to car travel and trucking.

Urban rail renovations happened, but they did not define the era’s growth as strongly as highways did; space program expansion centers on science and aerospace rather than broad public works; and waterway modernization, while important, did not produce the same nationwide mobility and economic impact. The highway project specifically represents the era’s signature public works effort that increased infrastructure and national connectivity.
