Tells the surprising story of how road construction helped to pave the way to the modern American state. Shows how the growing transportation needs of a steadily industrializing population changed political order from local to state and ultimately to federal governance.

Combining insights from urban, western, and environmental history, Elkind examines the ways that people's reactions to their natural surroundings drive both demand for improved public services and political reform. She traces public works development in the Gilded Age and Progressive Era to explain how these programs united each city with its suburban neighbors, creating new political entities and allowing Boston and Oakland to appropriate rural resources and thus overcome the environmental limits to their continued growth and prosperity. She also shows how, when the power of regionalism is turned to urban development, environmental and social costs are sometimes overlooked.
