A large research project, Recommended Specifications for Large-Span Culverts, is underway at the University of Massachusetts at Amherst under the direction of Prof Ernest T Selig. The objective is to develop reliability-based design specifications and construction criteria, for flexible and rigid large-span culverts. Funding is provided by the Association of State Highway and Transportation Officials (AASHTO) and the Federal Highway Administration (FHWA) and conducted through the National Co-operative Highway Research Programme.
