“The Interstate Highway Act literally brought Americans closer together,” President Bill Clinton said in 1996, referencing the bill that launched the 47,000-mile federal highway network. “We were connected city-to-city, town-to-town, family-to-family, as we had never been before. That law did more to bring Americans together than any other law this century.”
In his new book, Overbuilt , Erick Guerra, a professor at the University of Pennsylvania Weitzman School of Design, offers a markedly less rosy assessment of the US highway system. By blasting their way through cities, Guerra argues, interstate designers sacrificed urban wealth and quality of life, particularly within low-income neighborhoods.
