Infrastructure is something that we use every day, like roads, bridges, and tunnels, but probably never think too much about. However, in the United States, many parts of the country’s infrastructure are old, falling apart, and desperately need repair and upgrading. Tunnels especially are vital to transportation, and extremely dangerous when they collapse. This book explores eight tunnels of different types that are lifelines for transportation in the US, but are now at risk. Whether its Boston’s Big Dig, the twin railroad tunnels under the Hudson River, California’s Hetch Hetchey water system, or a rail tunnel in Baltimore that’s more than 100 years old, these tunnels are very important to the entire country. Without emergency repairs and expansion, these tunnels could fail, with catastrophic results.

IRP 2 contains selected papers from the 2016 International Workshop on Resiliency of Urban Tunnels, which address tunnels as a part of the complex urban infrastructure system and provide a basis for the development of a dynamic risk control and resilient design approach to urban tunnels.

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.

At the height of the Vietnam conflict, a complex system of secret underground tunnels sprawled from Cu Chi Province to the edge of Saigon. In these burrows, the Viet Cong cached their weapons, tended their wounded, and prepared to strike. They had only one enemy: U.S. soldiers small and wiry enough to maneuver through the guerrillas’ narrow domain. The brave souls who descended into these hellholes were known as “tunnel rats.” Armed with only pistols and K-bar knives, these men inched their way through the steamy darkness where any number of horrors could be awaiting them–bullets, booby traps, a tossed grenade. Using firsthand accounts from men and women on both sides who fought and killed in these underground battles, authors Tom Mangold and John Penycate provide a gripping inside look at this fearsome combat. The Tunnels of Cu Chi is a war classic of unbearable tension and unforgettable heroes. Praise for The Tunnels of Cu Chi “A claustrophobic but fascinating tale.”—The Wall Street Journal “Chilling . . . what war really was and how it was fought.”—The New York Times “Gripping . . . highly recommended.”—The Philadelphia Inquirer “Remarkable.”—The Washington Post

Tunnels and Underground Cities: Engineering and Innovation meet Archaeology, Architecture and Art contains the contributions presented at the World Tunnel Congress 2019 (Naples, Italy, 3-9 May 2019). The use of underground space is continuing to grow, due to global urbanization, public demand for efficient transportation, and energy saving, production and distribution. The growing need for space at ground level, along with its continuous value increase and the challenges of energy saving and achieving sustainable development objectives, demand greater and better use of the underground space to ensure that it supports sustainable, resilient and more liveable cities. This vision was the source of inspiration for the design of the logos of both the International (ITA) and Italian (SIG) Tunnelling Association. By placing key infrastructures underground – the black circle in the logos – it will be possible to preserve and enhance the quality of the space at ground level – the green line. In order to consider and value underground space usage together with human and social needs, engineers, architects, and artists will have to learn to collaborate and develop an interdisciplinary design approach that addresses functionality, safety, aesthetics and quality of life, and adaptability to future and varied functions. The 700 contributions cover a wide range of topics, from more traditional subjects connected to technical challenges of design and construction of underground works, with emphasis on innovation in tunneling engineering, to less conventional and archetypically Italian themes such as archaeology, architecture, and art. The book has the following main themes: Archaeology, Architecture and Art in underground construction; Environment sustainability in underground construction; Geological and geotechnical knowledge and requirements for project implementation; Ground improvement in underground constructions; Innovation in underground engineering, materials and equipment; Long and deep tunnels; Public communication and awareness; Risk management, contracts and financial aspects; Safety in underground construction; Strategic use of underground space for resilient cities; Urban tunnels. Tunnels and Underground Cities: Engineering and Innovation meet Archaeology, Architecture and Art is a valuable reference text for tunneling specialists, owners, engineers, architects and others involved in underground planning, design and building around the world, and for academics who are interested in underground constructions and geotechnics.

This updated and revised edition of Light at the End of the Tunnel is an exhaustive account of the Vietnam War that gives a total overview of the conflict. Starting with Ho Chi Minh's revolt against the French, Andrew Rotter takes the reader through the succeeding years as scholars, government officials, journalists, and others recount the important events and examine issues that developed during this tumultuous time. This book is essential for anyone who has an interest in truly understanding the Vietnam War. These readings will both educate and entertain students about this turning point in the history of the United States and, indeed, the world.

Of all of the wars in which the U.S. has been engaged, none has been as divisive as the conflict in Vietnam. The repercussions of this unsettling episode in American history still resonate in our society. Although it ended more than 30 years ago, the Vietnam War continues to fascinate and trouble Americans. The third edition of Light at the End of the Tunnel gives a full overview of the conflict. Starting with Ho Chi Minh's revolt against the French, editor Andrew J. Rotter takes the reader through the succeeding years as scholars, government officials, journalists, and others recount the important events in the conflict and examine issues that developed during this tumultuous time. This book is essential reading for anyone who has an interest in understanding the Vietnam War. The readings in it will enlighten students about this turning point in the history of the United States and the world. The third edition includes greater coverage of the Vietnamese experience of the war and reflects the growing interest in understanding the war as an international event, not just a bilateral or trilateral conflict.
