America's Interstates: The Next 50 Years: New Funding, Technology, Materials, and Methods Will Shape a Generation of Roads

The author outlines a century of interstate highway transportation--the half-century which has passed since President Eisenhower signed the Federal-Aid Highway Act of 1956, and the half-century still to come. The interstate system has helped to improve road safety, reduce local and state road congestion, and strengthen U.S. economic growth. With significant population growth (81.5%), as well as licensed drivers (163.5%) since 1956, and still more growth from today's statistics projected for the next fifty years (potentially 46.6% for population and 86.9% for licensed drivers), the interstate system needs to be expanding even faster than it is. Focus is needed on traffic growth's intermodal nature. Alternative interstate funding sources, including tolling and public private partnerships, are being discussed. Inserts include an interstate system origin timeline; a profile of a pioneering Arizona contractor's work in the 50s and 60s; how studying interstate design influenced a Pennsylvania bridge builder; how a paver in Iowa fared in the 60s and 70s; interstate-centered business development for a Houston contractor; how a Wyoming contractor learned on-the-job during interstate construction projects; and activities undertaken by the Kansas company awarded the very first interstate contract. Photographs spanning half a century of interstate highway construction and use complement the article.
