The Con-Struct™ Prefabricated Bridge System offers a sleek, modern profile for a 21st century sustainable design. The system incorporates a unique composite element which uses continuous hot-dipped galvanized steel tub girders with a precast concrete deck. The steel tub girders are stressed into a camber in a special forming system and the concrete deck is precast to them creating the composite element. When lifted and set, the concrete deck goes into compression eliminating temperature and shrinkage cracks thereby providing superior protection to the underlying steel reinforcement. The system’s precast concrete deck becomes the driving surface eliminating the need for a field applied, cast-in-place deck and/or wearing surface.
Con-Struct bridge prefabricated units are installed onto the bridge substructure. The steel beam trapezoidal shape requires no welding or cross frames. The steel beams are hot dipped galvanized to protect the steel from corrosion. The total superstructure weight of the Con-Struct Bridge System is typically less than a concrete beam superstructure, allowing for increased live loading of an existing foundation. Future widening can be done quickly and cost effectively with minimal effect to traffic as fascia beams can be produced with "for future widening" deck details.
