Not illustrated. 1906 Excerpt: ...so few highway Bridges are built of this material. A properly built concrete bridge is, as a general thing, cheaper than stone, and while more expensive than steel, is a structure which grows better with age rather than rusting out as steel is bound to do. Owing to the desirability of issuing this bulletin at as early a date as possible it was found impossible to prepare designs or to give exact information as to proper methods of construction of concrete bridges here. These will be given in the previously mentioned plans to be made by the Engineering College. The concrete for use in bridge structure is prepared as indicated on pages 58 and 59 for concrete culverts. LIEE AND COST OF BBIDGE AND CDXVEBT MATERIALS. Life of Bridges and Culverts.--Any statement of the life of ordinary materials for bridge and culvert construction must be largely guess work in which the factor of experience comes in to make the guess valuable. The common practice of railroads would make the life of the ordinary wooden bridge about fifteen years, providing it is not washed out by high water. The ordinary highway wooden bridge, however, ia very often subject to destruction on account of insecure foundations which are washed out long before the bridge has had time to decay. Wooden culverts are subject to very rapid decay and are ordinarily replaced every three or four years. Steel bridges are much more durable than wood and it is difficult to set any limit upon their life which will be even approximately accurate. Under favorable circumstances a bridge may last 75 years. The ordinary, light, flimsily constructed highway bridge, is not likely to last more than fifty years even if well cared for. The main cause of steel bridges giving away is the fact that they are so often erected up...
