This invention relates to a novel design of an open bottom box culvert
which can be used to enable roads, highways and other infrastructure to
cross streams without infringing on the wetted perimeter of a stream or
interrupting the stream gradient. More particularly, this invention
pertains to an innovative use of mineral soil (clay, silt, sand, gravel,
cobbles, boulders, broken rock, ice or mixtures of any or all of the
foregoing), concrete or wood abutments and metal such as steel, and in
some cases geosynthetics, to construct an open bottom box culvert
structure which can be erected over a stream or creek and enable
vehicular loads and other infrastructure to cross the stream or creek. An
open bottom box culvert comprising a pair of abutments spatially
positioned from each other, at least one corrugated steel plate spanning
the top portions of the two spatially positioned abutments, at least one
shear connector positioned above the corrugated steel plate and connected
thereto, and compacted soil disposed above and on each exterior side of
the pair of abutments, the corrugated steel plate and at least one shear
connector.
