Difference Between Bridge And Culvert
The drainage structure which facilitates a communication route for carrying road or railway traffic across an obstruction or depression with or without water is called a bridge.
The route of communication may be railway, roadway, cycle track, foothpath, or a combination of both of them, and the obstruction may be in the form of a river, stream, valley, channel, road, railway track etc.
Bridge having total span length greater than 6m & less than 60m.
Bridge having total span length greater than 6om.
Long Span Bridge:
Major Bridge having the main span length more than 120m.
A small bridge having total length of 6 m or less between the faces of abutments is known as a culvert.
These are permanent drainage structures which are mainly constructed to carry roadway or railway track over small streams or canals.
Difference Between Bridge And Culvert:
1. Bridge is constructed to allow the easy passage of traffic or community whereas culvert is made for the passage of water.
2. The length of a bridge is always more than 6 m, but the length of a culvert is 6 m or less than 6 m.
3. bridge is constructed over an obstruction, or depression or freeway, roadway, railway etc,
Culvert is made over small streams or canals.
4. Culvert is usually rectangular or circular in cross-section, having roof, walls and a floor.
