An embankment in transport is a structure made of compacted soil (clay or stone) used for the construction of roads , railways or canals , in order to avoid elevation differences on the way and not to change the terrain. For the same purpose, a recess is used if the height is higher than required.

Materials
The construction of the embankment is carried out using materials left after excavation. The embankment must be air- and waterproof, made of a compacted or completely non-porous material. It should provide appropriate support for the formation of a stable and long-term surface on which the road will be built.
Mound crossing
To cross the embankment without using flyovers, a series of tunnels is usually built, including a section of a viaduct with a high tensile strength (built of brick or metal) or a pair of stationary bridge supports.
