The construction of the Interstate Highway System in 1956 had profound implications for habitat fragmentation across North America. This extensive network of highways disrupted ecosystems and isolated wildlife populations, leading to significant environmental challenges. The development of infrastructure prioritized transportation and economic growth, often at the expense of natural habitats. The impacts of this fragmentation continue to be studied, emphasizing the need for balancing development with conservation efforts in contemporary planning.

The mass habitat fragmentation caused by the US Interstate Highway System since 1956 influenced Beat and later road poetry. Poets highlighted themes of disrupted natural connectivity and the search for freedom in a constrained landscape, reflecting the cultural shifts of the mid-20th century.
