As part of its effort to celebrate the 50th Anniversary of the Interstate Highway System, TRB has produced this specially themed issue of the TR News, which examines the history, legacy, lessons, and prospects of the Interstate system.
Celebrating the Interstate’s Anniversary
Celebrating the Interstate calls for a review of the conceptualization, the engineering feats, the funding, and the realization of a dream by many professionals working together for their entire careers—and for an assessment of our own accomplishments and challenges in extending the legacy of this great work.
How the Interstate System Came to Be: Tracing the Historical Process
The 1956 legislation that launched the Interstate Highway System was the product of choices made by many individuals and organizations over a span of almost 20 years, involving engineers, politicians, economists, visionaries, presidential panels, and more. A transportation historian traces out the formative theories, studies, models, initiatives, and debates.
The Exceptional Interstate Highway System: Will a Compelling New Vision Emerge?
The Interstate system is exceptional in American history because of the federal government’s extensive role in the system’s planning, financing, organizational structure, and research and development. But the consensus vision of the Interstate is eroding, this author notes—and the nation’s transportation future will be an ongoing contest among strongly held views and values.
