In 1916, Florida's road commission spent $967. In 1928 it spent $6.8 million. Tamiami Trail, originally projected to cost $500,000, eventually required $11 million. These roads were made possible by the 1920s Florida land boom, the advent of gasoline and diesel-powered equipment to replace animal and steam-powered implements, and the creation of a highway funding system based on fuel taxes. This book tells the story of the finance and technology of the first modern highways in the South.
