Short span precast bridges come in different configurations. Some include precast bridge decking with precast abutments that eliminate on-site concrete completely. This makes precast bridges one of the fastest to construct and in addition offers some of the least impact on the construction site. With the increased emphasis on protecting delicate ecological and wildlife areas, this has become more and more important.
Precast segmental bridge systems are the paramount of precast concrete complexity. PCI certified plant cast segments utilize factory-like precision for forming, reinforcing and post tension duct alignment as well as "match-casting" techniques to ensure the highest quality and a perfect fit when erected.
Bethlehem has built thousands of units equating to miles of elevated bridge deck.
