Divided Highways

"Anyone who has ever driven on a U.S. interstate highway or eaten at an exit-ramp McDonald’s will come away from this book with a better understanding of what makes modern America what it is." – Chicago Tribune "A fascinating work... with a subject central to contemporary life but to which few, if any, have devoted so much thoughtful analysis and good humor." – Minneapolis Star-Tribune "Divided Highways is the best and most important book yet published about how asphalt and concrete have changed the United States. Quite simply, the Interstate Highway System is the longest and largest engineered structure in the history of the world, and it has enormously influenced every aspect of American life. Tom Lewis is an engaging prose stylist with a gift for the telling anecdote and appropriate example."—Kenneth T. Jackson, Harvard Design Magazine "Lewis provides a comprehensive and balanced examination of America’s century-long infatuation with the automobile and the insatiable demands for more and better road systems. He has written a sprightly and richly documented book on a vital subject."—Richard O. Davies, Journal of American History "Lewis describes in a convincing, lively, and well-documented narrative the evolution of America’s roadway system from one of the world’s worst road networks to its best."—John Pucher, Journal of the American Planning Association "This brightly written history of the U.S. federal highway program is like the annual report of a successful company that has had grim second thoughts. The first half recounts progress made, while the second suggests that the good news is not quite what it seems."—Publishers Weekly "Lewis is a very talented and engaging writer, and the tale he tells—the vision for the Interstates, Congressional battles, construction, and the impact of new highways on American life—is important to understanding the shape of the contemporary American landscape."—David Schuyler, Arthur and Katherine Shadek Professor of the Humanities and American Studies at Franklin & Marshall College, author of Sanctified Landscape: Writers, Artists, and the Hudson River Valley, 1820–1909 In Divided Highways, Tom Lewis offers an encompassing account of highway development in the United States. In the early twentieth century Congress created the Bureau of Public Roads to improve roads and the lives of rural Americans. The Bureau was the forerunner of the Interstate Highway System of 1956, which promoted a technocratic approach to modern road building sometimes at the expense of individual lives, regional characteristics, and the landscape. With thoughtful analysis and engaging prose Lewis charts the development of the Interstate system, including the demographic and economic pressures that influenced its planning and construction and the disputes that pitted individuals and local communities against engineers and federal administrators. This is a story of America’s hopes for its future life and the realities of its present condition. Originally published in 1997, this book is an engaging history of the people and policies that profoundly transformed the American landscape—and the daily lives of Americans. In this updated edition of Divided Highways, Lewis brings his story of the Interstate system up to date, concluding with Boston’s troubled and yet triumphant Big Dig project, the growing antipathy for big federal infrastructure projects, and the uncertain economics of highway projects both present and future.

In Divided Highways, Tom Lewis tells the monumental story of the largest engineered structure ever built: the Interstate Highway System. Here is one of the great untold tales of American enterprise, recounted entirely through the stories of the human beings who thought up, mapped out, poured, paved - and tried to stop - the Interstates. Conceived and spearheaded by Thomas "the Chief" MacDonald, the iron-willed bureaucrat from the muddy farmlands of Iowa who rose to unrivaled power, the highway system was propelled forward through the pathbreaking efforts of brilliant engineers, argued over by politicians of every ideological and moral stripe, reviled by the citizens whose lives it devastated, and lauded as the greatest public works project in U.S. history.

This report describes common safety issues at median intersections on rural divided highways and presents innovative geometric and operational treatments for addressing those issues. Ten case studies illustrate how they have been applied in the field. The report includes recommendations for modifications to the AASHTO A Policy on Geometric Design of Highways and Streets (Green Book) and the Manual on Uniform Traffic Control Devices (MUTCD).

The Manual on Uniform Traffic Control Devices, or MUTCD, defines the standards used by road managers nationwide to install and maintain traffic control devices on all streets and highways. The Manual is important as it provides national traffic control standards for all public roads, and includes traffic signals, signs, roadway stencils, pedestrian crossings, and bicycle and pedestrian treatments. The Highway Design Handbook for Older Drivers and Pedestrians, being updated this year, is provided leading research information which may, as verified and tested, become standards in the MUTCD in future years. p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 13.0px Helvetica}
