In the 20th century, the United States built highway and aviation networks that transformed the country fueling unprecedented economic expansion, fostering new communities and connecting cities, towns and regions. Strong public-sector leadership along with private industry partnerships were the lynchpins to that success. States forged the path by identifying the needs and investing in key portions of the system, private industry brought innovation and resources, and the Federal Government provided an integrating vision, the policy roadmap and a funding framework that enabled the realization of a national system. |
