Road Shoulder
A road shoulder is a strip of land immediately adjacent to the traffic lane of a road not bordered by kerb & channel. The shoulder may be sealed in the case of highways and major roads, but it is typically unsealed and of a lesser depth and perhaps constructed of inferior material than the adjacent traffic lane.
