PRECAST PRESTRESSED CABLE-STAYED PEDESTRIAN BRIDGE FOR BUFALO INDUSTRIAL PARK

An all precast, prestressed concrete cable-stayed pedestrian bridge was constructed to transport workers across a busy four-lane highway to a major industrial park complex in San Pedro, Honduras. In designing the 30.8 m (101 ft) long structure, special attention was given to creating an aesthetic harmony between the bridge and the entrance canopy as well as the other buildings in the Bufalo Industrial Park. This article presents the design options, architectural concept, design considerations and particularly the design of connections, construction highlights, and especially the role that the nearly 150 precast concrete components played in erecting the bridge. It is concluded that the design concepts and construction method, which proved to be efficient and economically successful in Honduras, can be applied in other parts of the world.
