Excerpt from Bridges a Study in Their Art, Science and Evolution The purpose of this book is threefold. First: to give a method for the application of funda mental architectural principles to the design and criticism of bridges; to point out that the modern bridge should not, as is sometimes stated, be exempted from the same rules of art that apply to other architectural works; and to make a plea for thorough architectural train ing of the Civil Engineer that his tremendously important works may be as inspiringly beau tiful as they are economically sound. Second: to present the historical background of the Modern Bridge, showing how bridge building developed from the earliest time to the present day; how it has been influenced by social, political, and economic conditions; and picturing the most beautiful and interesting bridges of each period. Third: to present a selection of photographs of artistic bridges of all types; which it is hoped will not only interest the layman but will furnish valuable inspiration to engineers and architects who are engaged in designing bridges. Not all of the designs pictured are to be considered as perfect, but they all have enough artistic merit to make their study worth while, and they show how their designers have solved the special problems involved.

From the earliest times when bridges were just logs or stepping stones placed across streams or small gullies, to the modern era with its complicated, highly engineered structures of stone, concrete and steel, bridge building has evolved into a sophisticated marriage of architecture and engineering--an aesthetically pleasing blend of art and science. This illustrated study explores that evolution by examining the principles of bridge design and construction from the times of the Romans to the first decades of the twentieth century.
