Excerpt from Concrete Bridges and Culverts, for Both Railroads and Highways Bridges of solid concrete are superior to those of any other material. They are as permanent as stone, and have a less cost. Masonry bridges and aqneducts built by the Romans are still standing, and some of them in use. A few old cast iron bridges remain, dating back a century or more, but a majority of the modern ones built of wrought iron and steel have a very limited existence. Forty years ago, steel bridges were believed to be permanent structures, but it is now well known that they do not generally last longer than from twenty to thirty years. Solid concrete bridges are superior to those in which reinforcing metal is required for resisting tensile stresses in the arch ring. Continuous water-soaking reduces the adhesion of concrete to steel by about 100 percent, and the effect of shocks and vibrations also tends to destroy the bond. It frequently occurs that cracks develop, sufficiently large to admit water, and when water and moisture reach the reinforcing metal, it is then only a few years before the metal is destroyed by rust. An old wire suspension bridge that recently failed, was examined and reported on by the writer, and it was found that failure occurred because of the rusting and breaking of the wire cables embedded in the anchorage.

Excerpt from Highway Bridges and Culverts Bridge building in the United States is of comparatively recent accomplishment. The early settlers were compelled to ford the streams or cross them on rafts or in dugouts. When Washington crossed the Delaware with his army, there were no bridges over that river, and history records many instances of streams being forded with untold hardship and the consequent disasters and delays. Such incidents become serious matters when, for example, physicians are unable to reach the sick or injured because Of impassable fords or are compelled to expose themselves to unnecessary danger. Traffic conditions in general are demoralized by unsafe bridges or culverts. Pontoon bridges have served temporary needs in many instances, but especially in warfare. Mention is made Of their use very early in history, and one Of the most notable occasions was when the Per sian army under Xerxes crossed the Hellespont on two pontoon bridges consisting, one of 360 vessels and the other of 314. These were anchored head and stern alongside each other, with their keels in the direction of the current. The Romans had wickerwork vessels covered with hides destined to support the timber platforms of a bridge. These formed a part of the train Of their armies throughout the history of the Empire until 476 A. D. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
