Box Beam
Box beams are prestress bridge beams with a central void to reduce weight. Box beams are typically set on abutments or piers and can be a composite type in which concrete is poured on top of the box beams or can be paved over with asphalt.
Looking for a bridge system that is beyond the capabilities of a three sided flat top or arch system? Then a prestress box beam bridge system might be the right option for you upcoming project. With spans up to 80’ or more, these can do what a box culvert or precast bridge cannot. With a full engineering department on staff, contact us about how we can build a solution together.
