Conveyance structure that provides a means for the water to pass under a road or railroad A culvert can be built out of several different structural means as Corrugated Metal Pipe (CMP), Precast Concrete Pipe (PCP), and Free Flow Box Culverts specifically made for the culvert
Any covered structure, not classified as a bridge, that constitutes a transverse drain, waterway, or other opening under a road, railroad, canal, or similar structure (Bates and Jackson 1980); any covered structure that acts as a drain (Bates & Jackson, 1987)
A conduit or passageway under a road, trail, or other obstruction that may or may not be designed to convey water (3) A culvert is generally used to divert a stream or rainfall runoff to prevent erosion or flooding on highways In the Wildlife Crossings Toolkit, a culvert is one of two basic types of underpasses for wildlife to cross under moving traffic; the other basic type is a bridge See Crossing Structure or specific type of culvert (Box, Continuous, Bottomless) Cumulative Effects The combined effects of all human activities on a defined area Cumulative effects assessments investigate the collective impacts of all historic, present, and predicted human activities in an area (1)
a small bridge entirely below the elevation of the roadway surface, with no integral parts Structures less than 20 feet in span are culverts, even though they support traffic loads directly Structures over 20 feet in span and parallel to the roadway are bridges
a culvert is another word for a stormwater pipe which is not connected up to the main stormwater system There are generally two types of culverts - vehicle crossing culverts which are a short length of pipe running under driveways (used on roads that do not have kerb and channeling); and road crossing culverts which are pipe systems running under the road which usually take water from a stream from one side of the road to the other (under the road)
