An examination of the condition of infrastructure and the estimated cost of bringing roads and bridges to a safe and accepted condition in Illinois, Minnesota, Ohio, and Wisconsin.
Learn about the geography, climate, history, and economy of the midwest region of the United States.
"Midwest" for purposes of this study includes Illinois, Minnesota, Ohio, and Wisconsin.
During the American colonial period, what would become the Midwest was the "backcountry," or the area behind the coastal population centers. It was rural and rough, the sort of place that fueled populist resistance to the federal taxation of whiskey. At the time of the Revolution, it was The West, often undifferentiated between north and south and largely associated with Kentucky. In the early years of the republic, however, the regional differentiation deepened and grew until the latter half of the 19th century, when the Midwest emerged as a fully formed region. The essays in this book help explain this process of region-making. Contributors: Christa Adams Brie Swenson Arnold Terry A.

A symbol of Indiana's past, the covered bridge still evokes feelings of nostalgia, romance, and even mystery. During the 19th century, over 500 of these handsome structures spanned the streams, rivers, and ravines of Indiana. Plagued by floods, fire, storms, neglect, and arson, today fewer than 100 remain. Marsha Williamson Mohr's photographs capture the timeless and simple beauty of these well-traveled structures from around the state, including Parke County—the unofficial covered bridge capital of the world. With 105 color photographs, Indiana's Covered Bridges will appeal to everyone who treasures Indiana's rich architectural heritage.
Worldwide, integral type bridges are being used in greater numbersin lieu of jointed bridges because of their structural simplicity,first-cost economy, and outstanding durability. In the UK and theUS states of Tennessee and Missouri, for example, the constructionof most moderate length bridges is based on the integral bridgeconcept. The state of Washington uses semi-integral bridges almostexclusively, while, depending on subfoundation characteristics, thestate of Ohio and others use a mix of these two bridge types. Integral and Semi-Integral Bridges has been written by apracticing bridge design engineer who has spent his entire careerinvolved in the origination, evaluation and design of such bridgesin the USA, where they have been in use since the late1930’s. This work shows how the analytical complexity due tothe elimination of movable joints can be minimized to negligiblelevels so that most moderate length bridges can be easily andquickly modified or replaced with either integral or semi-integralbridges. Bridge design, construction, and maintenance engineers; bridgedesign administrators; graduate level engineering students andstructural research professionals will all find this bookexceptionally informative for a wide range of highway bridgeapplications.
