Book Description
All phases of road developmentâ€"from construction and use by vehicles to maintenanceâ€"affect physical and chemical soil conditions, water flow, and air and water quality, as well as plants and animals. Roads and traffic can alter wildlife habitat, cause vehicle-related mortality, impede animal migration, and disperse nonnative pest species of plants and animals. Integrating environmental considerations into all phases of transportation is an important, evolving process. The increasing awareness of environmental issues has made road development more complex and controversial. Over the past two decades, the Federal Highway Administration and state transportation agencies have increasingly recognized the importance of the effects of transportation on the natural environment. This report provides guidance on ways to reconcile the different goals of road development and environmental conservation. It identifies the ecological effects of roads that can be evaluated in the planning, design, construction, and maintenance of roads and offers several recommendations to help better understand and manage ecological impacts of paved roads.

Book Description
In Roads Were Not Built for Cars, Carlton Reid reveals the pivotal—and largely unrecognized—role that bicyclists played in the development of modern roadways. Reid introduces readers to cycling personalities, such as Henry Ford, and the cycling advocacy groups that influenced early road improvements, literally paving the way for the motor car. When the bicycle morphed from the vehicle of rich transport progressives in the 1890s to the “poor man’s transport” in the 1920s, some cyclists became ardent motorists and were all too happy to forget their cycling roots. But, Reid explains, many motor pioneers continued cycling, celebrating the shared links between transport modes that are now seen as worlds apart. In this engaging and meticulously researched book, Carlton Reid encourages us all to celebrate those links once again.

Book Description
The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Book Description
"TRB National Cooperative Highway Research Program (NCHRP) Synthesis 485: Converting Paved Roads to Unpaved explores how common and under what conditions paved roads are converted to unpaved. NCHRP Synthesis 485 found that the practice of converting paved roads to unpaved is relatively widespread; recent road conversion projects were identified in 27 states. These are primarily rural, low-volume roads that were paved when asphalt and construction prices were low. Those asphalt roads have now aged well beyond their design service life, are rapidly deteriorating, and are both difficult and expensive to maintain. Instead, many local road agencies are converting these deteriorated paved roads to unpaved as a more sustainable solution. According to the report, local road agencies have experienced positive outcomes by converting roads. Many local road agencies reported cost savings after converting, compared with the costs of continuing maintenance of the deteriorating paved road, or repaving. One key to successful conversion is early involvement of the public in the planning process. Other techniques that can be used to improve the overall results of a project include treating or stabilizing granular surfaces to control dust, limiting the rate of aggregate loss, and reducing motor grader/blade maintenance frequency. Stabilization procedures can also improve safety, increase public acceptance, and reduce life-cycle costs and environmental impacts after a conversion has taken place."--Publisher's description.

Book Description
Discover the twists and turns of one of America’s great infrastructure projects with this “engrossing history of the creation of the U.S. interstate system” (Los Angeles Times). It’s become a part of the landscape that we take for granted, the site of rumbling eighteen-wheelers and roadside rest stops, a familiar route for commuters and vacationing families. But during the twentieth century, the interstate highway system dramatically changed the face of our nation. These interconnected roads—over 47,000 miles of them—are man-made wonders, economic pipelines, agents of sprawl, uniquely American symbols of escape and freedom, and an unrivaled public works accomplishment. Though officially named after President Dwight D. Eisenhower, this network of roadways has origins that reach all the way back to the World War I era, and The Big Roads—“the first thorough history of the expressway system” (The Washington Post)—tells the full story of how they came to be. From the speed demon who inspired a primitive web of dirt auto trails to the largely forgotten technocrats who planned the system years before Ike reached the White House to the city dwellers who resisted the concrete juggernaut when it bore down on their neighborhoods, this book reveals both the massive scale of this government engineering project, and the individual lives that have been transformed by it. A fast-paced history filled with fascinating detours, “the book is a road geek’s treasure—and everyone who travels the highways ought to know these stories” (Kirkus Reviews).

Book Description
Paved Roads & Public Money describes the evolution of transportation systems in modern Connecticut. It is the second book in a two-volume study that begins with the bicycle craze of the 1880s, and ends with the efforts of the Malloy and Lamont administrations to revitalize Connecticut transportation in the twenty-first century. The story includes aviation, highways, bridges, ferries, steamboats, canals, railroads, electric trolleys, and water ports in Connecticut and along the multi-state travel corridor from New York to Boston. Drawing on a wide array of primary material, Richard DeLuca examines how land, law, and technology have shaped the state and its transportation systems, giving special attention to the state's two largest transportation monopolies: the New Haven Railroad and the Connecticut Department of Transportation. The book focuses on key events in the development of transportation and legislation. It is arranged chronologically, and by highlighting themes from each period shows the implications of the state's transportation history on current debates about infrastructure and funding. It features 50 illustrations and three appendices: population by geomorphic region, a list of controlled access highways, and a list of notable highway bridges.
