LOW-COST WATER CROSSINGS

Travesías de agua de bajo costo = Ouvrages de franchissement d'eau économiques

This compendium is a product of a 3-year project to enhance rural transportation in developing countries by providing improved access to existing information on the planning, design, construction and maintenance of low-volume roads. The compendium concerns stream and river crossings. lt introduces many of the types of low-water crossings that are available and discusses the design, construction, and economic features of these crossings. Low-volume roads can be built with fords, dips, or submersible bridges. This reduces the initial investment. Later, they can be upgraded by construction of large culverts or bridges as warranted by the cost of delays. The compendium also reviews the general requirements for proper roadway drainage. lt includes the grading and shaping of the road so that falling water or water running down from higher ground will drain away with a minimum of damage. The eight texts that have been reprinted in full or in excerpted portions are: Handbook of Methods and Procedure for Low Cost Service Roads (Texas Highway Department, 1946); Use of Gabions for Low Water Crossings on Primitive or Secondary Forest Roads (U.S. Forest Service, 1973); Design and Construction of Low Water Dips, from Construction and Maintenance Bulletin No. 6 (Texas Highway Department 1951); Causeways or Submersible Bridges (Journal of the Indian Roads Congress, Vol. 16, No. 3, April 1952); FMS-34: Engineer Field Data, Chapter 5 and Section 1 of Chapter 7 (U.S. Department of the Army, 1976); The Bailey and Uniflote Handbook (Acrow Press, 1974); Opportunities for Cost Reduction in the Design of Transport Facilities for Developing Regions (Institute for Transportation and Traffic Engineering, University of California, Berkeley, 1970); and Bridges, Viaducts and Ramps from the Handbook of Highway Engineering (Van Nostrand Reinhold Company, 1975).
