Box culvert is a usually default buried structure type that serves a variety of purposes. It is typically used for conveying water and also frequently used for pedestrian or cattle underpasses. Box culvert can be provided in both ‘Precast Concrete Box Culvert’ and ‘Cast-In-Place Concrete Box Culverts’ form. Currently, most box culvert installations are provided in precast form due to the huge reduction of time for place production and construction.

Design new reinforced concrete culverts and extensions to existing culverts subjected to either earth fill and/or highway vehicle loading in accordance with the AASHTO LRFD Bridge Design Specifications. Precast concrete box culvert will be used in this design tutorial.
