Precast/prestressed concrete became the solution of choice in replacing an old non-functional footbridge at Washington State University in Pullman, Washington. The new $280,000 pedestrian bridge has spans of 24, 64, 24 ft (7.32, 19.52, 7.32 m), in which the two end spans are straight and the middle span is parabolic. Only seven precast components - three U-shaped girders and four piers -were needed to build the structure. The end result is a magnificent bridge that is very functional, was erected on schedule with minimal disruption of traffic and was within budget. This article presents the owner's requirements and design considerations, as well as the production, hauling, and erection highlights of the project.
