The year 2006 celebrates the 50th anniversary of the U.S. Interstate System, the most incredible road system in the world. Created by Dwight D. Eisenhower, whose WW II experiences taught him the necessity of a superhighway for military transport and evacuation in wartime, today's Interstate System is what connects our coasts and our borders, our cities and small towns. It's made possible our suburban lifestyle and caused the vast proliferation of businesses from HoJos to Holiday Inns. And if you order something online, most likely it's a truck barreling along an interstate that gets the product to your door. Written by bestselling author Dan McNichol, The Roads that Built America is the fascinating story of the largest engineering project the world has ever known.

Bridging the gap between architecture and infrastructure, Easterling views architecture as part of an ecology of interrelationships and linkages, and she treats the expression of organizational character as part of the architectural endeavor. The dominant architectures in our culture of development consist of generic protocols for building offices, airports, houses, and highways. For Keller Easterling these organizational formats are not merely the context of design efforts—they are the design. Bridging the gap between architecture and infrastructure, Easterling views architecture as part of an ecology of interrelationships and linkages, and she treats the expression of organizational character as part of the architectural endeavor. Easterling also makes the case that these organizational formats are improvisational and responsive to circumstantial change, to mistakes, anomalies, and seemingly illogical market forces. By treating these irregularities opportunistically, she offers architects working within the customary development protocols new sites for making and altering space. By showing the reciprocal relations between systems of thinking and modes of designing, Easterling establishes unexpected congruencies between natural and built environments, virtual and physical systems, highway and communication networks, and corporate and spatial organizations. She frames her unconventional notion of site not in terms of singular entities, but in terms of relationships between multiple sites that are both individually and collectively adjustable.

The author maintains that American politics, institutional arrangements, and political culture have prevented the development of a comprehensive, integrated, intermodal transportation policy in the United States. Dilger makes his argument by examining the development of the national governmental authority in both surface and air transportation. Each transportation mode—highways/mass transit, Amtrak, and civilian air transportation—is examined separately, assessing their development over time and focusing on current controversies, including, but not limited to, the highway versus mass transit funding issue; the recent decentralization of decision making authority on surface transportation policy; Amtrak's viability as an alternative to the automobile; and current antiterrorist policies' effect on transportation policy.

In The American Road Katherine M. Johnson develops a bold new theory for how the American highway system has taken on such outsized scale and complexity by emphasizing the emergence of a powerful administrative apparatus in the American federal system. Established in 1914 expressly to intervene in the congressional debates of the era, the American highway bureaucracy consisted of forty-eight state highway officials acting in and through their self-organized association, the American Association of State Highway Officials. Johnson’s central argument is that this new institution occupied a similar position relative to the American state as political parties and courts did. The capacity to organize across a complex constitutional order enabled it to control the purpose and allocation of federal highway aid for the better part of the twentieth century. Johnson investigates this new conception of the American highway bureaucracy, showing specifically where and how that extraconstitutional authority emerged, expanded, and manifested itself in the legislative history, physical dimensions, and geographical reach of the emerging highway system. The American Road reveals that all of the major highway legislation approved by Congress from 1916 to 1941 was collectively developed and advanced by state and federal highway bureaucrats drawing on the new authority conferred by the system of federal grants-in-aid, which required state legislatures to provide a state matching grant and local governments to relinquish control over decisions of location and design. The capacity to advance their policy aims through both the advice of experts and the will of the states not only secured the new highway program against renewed opposition in Congress in the 1920s but also won the strong support of the motor vehicle industry and set the stage for even more impressive policy gains of the 1930s when highways became the largest category of federal emergency public works. That collective authority, however, required a high threshold of consensus to secure and maintain, producing not just a narrow one-size-fits-all approach to technical issues but also a striking incapacity to respond to changing conditions. Johnson completes her compelling narrative by identifying the source of the interstate highway plan, first proposed in 1939 and finally funded in 1956, in the internal dynamics of and external threats to that extraconstitutional authority.
