An economical retro-reflective roadway marker of high strength plastic materials having a reflective top assembly having a resilient portion that is curved to raise the reflective top assembly and a recessed base assembly or roadway depression. The reflective top assembly comprises a series of steps having reflective tape or other reflective material on the step risers. The steps interconnect spaced apart, parallel curved sidewalls that raise the steps above a road surface. The curved sidewalls serve to guide snowplow blades, or the like, over the steps as the resilient portion of the top surface is flexed downwardly. An end base plate forms a continuation of the steps. When it is only necessary to provide reflection for one-way traffic, the end base plate is secured to the road surface and a depression is made in the road surface to receive the top assembly. As a wheel, snowplow blade, or the like, passes over the marker, the resilient portion temporarily deflects down into the depression, thereafter returning to its prior position. For two-way traffic, however, a modified upper assembly and a special base assembly are provided.
