Describing and detailing the boring of major railroad tunnels throughout Canada, the United States, and Mexico, this book covers the period from the creation of Virginia's Blue Ridge Tunnel in the 1850s to Copper Canyon's Continental and El Descanso tunnels in the early 1960s. Other notable tunnels featured here include Massachusetts' notoriously expensive and slow-progressing Hoosac Tunnel; Colorado's rail and water Moffat Tunnel; Montana's Flathead Tunnel; and several major tunnels along the Canadian Pacific's main line. In addition to providing details on the tunnels, the author considers the reasons they were created, their engineers, and their use. The book includes more than 50 period and contemporary photos. A glossary explains concepts related to railroad construction and maintenance.

Conventional narratives describe the United States as a continental country bordered by Canada and Mexico. Yet, since the late twentieth century the United States has claimed more water space than land space, and more water space than perhaps any other country in the world. This watery version of the United States borders some twenty-one countries, particularly in the archipelagoes of the Pacific and the Caribbean. In Borderwaters Brian Russell Roberts dispels continental national mythologies to advance an alternative image of the United States as an archipelagic nation. Drawing on literature, visual art, and other expressive forms that range from novels by Mark Twain and Zora Neale Hurston to Indigenous testimonies against nuclear testing and Miguel Covarrubias's visual representations of Indonesia and the Caribbean, Roberts remaps both the fundamentals of US geography and the foundations of how we discuss US culture.
