Opis

Before the advent of the automobile, railroads crossed the United States, making relatively quick travel possible for the masses. This book chronicles the development of metal truss and related bridges in Maine, New Hampshire and Vermont from the 1860s to 1940. Highlighted are the various bridge types and their inventors, the historical changes in the highway and railroad networks that resulted in these bridges being built, the rise of state bridge-building agencies, developments in the field of civil engineering as they related to bridge construction, and preservation trends. While many notable metal bridges of the past are discussed in context with these topics, the book's main focus is a detailed account of the remaining historic bridges.
