Creative Concrete Bridge Solutions: Precast Concrete Bridges beyond “Traditional” Culvert Applications

This paper describes how precast culverts are no longer limited to the traditional “culvert applications”. Economical, effective and efficient answers are now available for a wide variety of applications including airport, railroad, environmental, storm water and more. Solutions are being provided to answer the highway industry’s most urgent need – replacement of the aging and deficient small bridge inventory. Modern technology has advanced precast concrete bridge design. Larger clear spans allow for unobstructed waterways for environmental applications, minimize stream mitigation costs, reduce permitting time and reduce maintenance costs. Precast solutions allow design engineers to realize the “Get In, Get Out, Stay Out” concept. Design engineers are no longer limited to the use of multiple spans for clear span ranges up to 48 -ft. These larger sectio ns also can accommodate significant structural dead loads and large live loads such as the 1,600,000 -pound aircraft Anatov AN225 loading. Today’s presentation will feature several innovative projects designed using the CON/SPAN a Bridge System that were completed in the last two years: a quadruple cell traffic and service tunnel under the runway of Houston Airport, a 4900 -ft long extension of the Metrolink rapid transit system in St. Louis, Missouri; a nine cell, cost saving and aesthetic 446 -ft stream crossing in Loudoun County, Virginia; and an 1100-ft stream enclosure Army Corps of Engineers project in Cincinnati, Ohio.
