Book Description
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 countrys 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 Bostons Big Dig, the twin railroad tunnels under the Hudson River, Californias Hetch Hetchey water system, or a rail tunnel in Baltimore thats 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.

Book Description
Rivers have tumbled down mountains and floated lazily through flat plains in the US since long before Europeans first came to this continent. They were the only highways Native Americans used or needed. Even Americas first settlers found it much easier to travel on the waterways than to build roads through the forests. Today our inland waterways carry millions of tons of cargo each year. But our waterways have not received the attention needed to continue their important role in the commerce of our country. Waterways infrastructure such as locks, dams, channels, and levees need help. Many elements are old and need repair or replacement. Expanded infrastructure would allow the US to increase shipping on the waterways. Shipping via water has always been cheaper than shipping by land and remains so today. The US economy can only benefit from investment in our inland waterways.

Book Description
Imagine a world without airports! Air travel has changed the way we live and work, but no one would be able to travel without airports. Over the past 100 years, air travel has gone from an unusual adventure to an everyday event. Discover the stories behind eight major U.S. airports, including how they were built, how many people they serve, and the problems and solutions that have changed air travel over the decades. Airports are a vital part of America's infrastructure, and their construction and expansion tell an important story about how Americans live and work today.

Book Description
Has anyone actually seen a bridge being built in America? This editor has travelled for almost 40 years in America without seeing a single one being constructed -- and few even being repaired. Some critics point out that America has built excellent bridges in Vietnam and Iraq which indicates that the knowledge base remains intact. Others say that individual states cannot feed their armies of bureaucrats and fund their plush pensions and health care programs and still expect to build bridges. And the federal government cannot be counted on for much of anything useful. This book presents recent reports focusing on this part of America's crumbling infrastructure.

Book Description
This book gives an account of how the U.S. freight transportation system has been impacted and “globalized,” since the 1950s, by the presence of the shipping container. A globally standardized object, the container carries cargo moving in international trade, and it utilizes and fits within the existing transportation infrastructures of shipping, trucking and railroads. In this way it binds them together into a nearly seamless worldwide logistics network. This process occurs not only in ocean shipping and at ports, but also deep within national territories. In its dependence on existing infrastructural systems, though, the network of container movement as it pervades domestic space is shaped by the history and geography of the nation-state. This global network is not invariably imposed in a top-down manner—to a large degree, it is cobbled together out of national, regional and local systems. Heins describes this in the American context, examining the freight transportation infrastructures of railroads, trucking and inland waterways, and also the terminals where containers are transferred between train and truck. The book provides a detailed historical narrative, and is also theoretically informed by the contemporary literature on infrastructure and globalization.
