A barrier system located between an access area such as a road and an adjoining hazard has barrier elements mounted on posts secured to inwardly directed, buried and anchored beam members, which extend below the surface of the access area. The posts may be cantilevered from the beams, with bracing means connecting the system members. The post, beam and its anchor members may be pivotally linked, so as to be foldable. The beam anchor may be a cable connected beneath the road to an oppositely located beam and post. The posts can project below the beam support means, and can have stabilizing blades near their lower ends. Posts can be made withdrawable, and can be cross-braced to adjacent posts.
