COST-EFFECTIVE LOW-VOLUME-ROAD STREAM CROSSINGS

Because of their high relative cost and degree of importance in any transportation system, stream-crossing structures warrant careful site selection, structure type selection, and design. All too often a stream is spanned with a conventional structure merely because that is the way it has always been done, or a replacement structure is designed to the same standard as the previous structure without consideration of other options. The features to look for in selecting a stream-crossing site for low-volume roads are discussed and ideas are provided on improving communication among the road locators and designers, the bridge designers, and other necessary specialists. Some of many possible alternatives to conventional bridge-type crossings are offered, and ways are suggested to make a design and contracting system more cost effective through the use of standard drawings and contractor design options. Several examples are included of how low-water crossings can be used. These examples show some of the many possible variations that can be included in the design of low-water crossings. Costs are used to compare the low-water crossings and the design alternatives. Costs of the low-water crossings are based on actual bid prices, whereas costs of the design alternatives are based on the engineer's estimate. (Author)
