The present invention provides a pole (10) for a road, a method to manufacture the same, and a separator for a road including the pole (10). The pole for the road comprises: a pole body (14), a hollow upper body (142), and a hollow lower body (144) integrated with the upper body (142). A length (L11) of the upper body (142) is longer than the lower body (144), and a thickness (T12) of the lower body (144) is thicker than the upper body (142); thus a restoring force of the lower body (144) is higher than the upper body (142). |
