Abstract
Abstract A highway marker comprises a metallic body of rectangular shape adapted for nesting and enclosure within a recess formed in a roadway. Said body has upright side and end walls and a flat bottom wall and with opposed downwardly and inwardly inclined inner side walls and downwardly and inwardly inclined inner end walls. A transverse rib of A-shape extends between said inner side walls intermediate their ends and has a pair of oppositely arranged downwardly and inwardly inclined side walls, all said inclined walls extending to and merging with said bottom wall. A reflectorized layer is applied to each inclined wall. A layer of adhesive material is applied to the bottom and side walls adapted for securing the marker within a roadway recess so as to be flush with the top surface of said roadway.
