Box Beams are typically used for 80′-118′ bridge spans. The design allows for a typical 4′ width section to include integral voids which reduce the product weight and are often used when box depth and speed of construction are part of the design criteria. Placed side by side at the jobsite, these sections are bolted or welded together, the shear key between the sections is grouted and then can be ready for traffic or an overlay.
Standard box beam design is typically governed by the State, County or Agency design criteria. In the Pacific Northwest using a nominal 4′ wide box beam at depths of 33″, 39″, 42″ and 48″ provides the most cost effective use of the section.
