A traffic marker and housing is disclosed, intended for installation in a road surface to provide delineation of traffic lanes. The marker comprises a platform installed flush with the road surface, with two bridges projecting upwardly from the platform, the bridges including ramp portions, and a reflector carried between the bridges in protected fashion. The platform extends beyond the ends of the bridges. The two bridges are aligned with the direction of traffic flow and offset from each other by an angle corresponding to the angle presented by an oncoming snowplow blade, so that the snowplow blade impacts both substantially simultaneously. The ramp portions are coplanar, and the plane of the ramp portions is offset by the same angle as the bridges. Apertures in the bridges provide an automatic cleaning feature, produced by the effect of passing vehicles. The bridges have angled outside edges to minimize inconvenience to traffic.
