Every day, millions of people across the United States drive on public roads, purchase goods shipped to stores on trains, and take flight across the country. They have access to water at the turn of a handle and electricity at the flip of a switch. These conveniences all come as the result of the nation's vast and highly developed infrastructure. Readers will find out how this infrastructure was put in place and what it takes to maintain it.
