A housing for a sunken electric road track configured to conductively provide electric power to a vehicle is presented. The housing comprising: a bottom plate extending in a longitudinal direction (L); opposing side walls protruding from the bottom plate; and opposing lateral flanges extending in the longitudinal direction (L), the opposing lateral flanges extending in the longitudinal direction (L) forming lateral protrusions for providing anchoring of the housing in a fixating mass used for fixating the housing in a groove of a roadway (40). Also, a sunken electric road track comprising such a housing is presented as well as a method for arranging a sunken electric road track along a road.

This support (36), as a profile in an electrically insulating material, comprises a substantially planar upper surface (50), provided with a longitudinal flute (60) intended for receiving a track segment, and a longitudinal groove (70) intended for receiving a low voltage electric power supply cable; and a lower surface (52) intended to bear upon a base for maintaining the support in the roadway. It is characterized in that the lower surface (52) is curved, preferably V-shaped, so that the support is concave so as to be at least transversely maintained in a recess with a mating shape, made in the base.
