This book invites the reader to step back in time and imagine the days when ancestors traveled through wooden spans to reach their daily destinations. Starting in the early 1800s, Pennsylvania's rich forests provided natural material for the construction of more than 1,500 covered bridges across the state. The first covered bridge was built in 1805. Pennsylvania's Covered Bridges looks at the earliest covered bridges as well as those that have survived modern progress. Images also show rare railroad covered bridges that have been saved from destruction over the years.

The state of PA includes over 25,000 bridges, and the Penna. Dept. of Transp. (PennDOT) is constantly involved with the maintenance, repair, rehabilitation or replacement of highway bridges. Because PennDOT¿s responsibilities include a consideration of historic qualities in planning transportation projects, a reliable list of bridges that had historic significance was needed. A project was undertaken to survey and evaluate PA¿s bridges and to compile a list of bridges significant in the dev¿t. of PA¿s highway system and bridge engineering history. There were 180 bridges that were deemed as significant and worthy of preservation. This publication details those bridges. Extensive and detailed drawings, maps and photos.

This book chronicles the development of metal truss and related bridges in Maine, New Hampshire and Vermont from the 1860s to 1940: the various types and their inventors, historical changes in the highway and railroad networks that caused these bridges to be built, the rise of state bridge-building agencies, developments in the field of civil engineering, and preservation trends. While many notable metal bridges of the past are discussed in the context of these topics, the book's main focus is a detailed account of the remaining historic bridges.

Fog, tide, ice, and human error--before the American Revolution those who ventured to cross the vast Hudson Valley waterway did so on ferryboats powered by humans, animals, and even fierce winds. Before that war, not a single Hudson River bridge or tunnel had been built. It wasn't until Americans looked to the land in the fight for independence that the importance of crossing the river efficiently became a subject of serious interest, especially militarily. Later, the needs of a new transportation system became critical--when steam railroads first rolled along there was no practical way to get them across the water without bridges. Crossing the Hudson continues this story soon after the end of the war, in 1805, when the first bridge was completed. Donald E. Wolf simultaneously tracks the founding of the towns and villages along the water's edge and the development of technologies such as steam and internal combustion that demanded new ways to cross the river. As a result, innovative engineering was created to provide for these resources. From hybrid, timber arch, and truss bridges on stone piers to long-span suspension and cantilevered bridges, railroad tunnels, and improvements in iron and steel technology, the construction feats that cross the Hudson represent technical elegance and physical beauty. Crossing the Hudson reveals their often multileveled stories--a history of where, why, when, and how these structures were built; the social, political, and commercial forces that influenced decisions to erect them; the personalities of the planners and builders; the unique connection between a builder and his bridge; and the design and construction techniques that turned mythical goals into structures of utility and beauty.
