A post structure for installation along a street or road with a base supporting the post structure in a yieldable manner. A coupling joining the base and post structure includes a resilient member urging the post structure into a normal, pre- determined position on the base. An upper end of the base serves as a fulcrum for momentary post structure movement. A modified form of the yieldable support includes a housing with spring and fastener assembly with the housing having inclined surfaces which cooperate with inclined surfaces on the base upper end, insuring return of the tipped post structure back to the pre-determined relationship with the base after momentary displacement.
