The prestressed concrete truss bridge system has been outlined. The technology can provide remarkable cost-saving and construction benefits compared to prestressed concrete box girder bridge construction. The paper has also shown (through several examples) that the panel point is a critical structural element in the design of the composite truss bridge. This is the structural component that differentiates the composite truss bridge from the conventional prestressed box girder system. The authors believe that the technology will continue to provide competitive design solutions for bridge design engineers.
