A portable roadway warning device comprises one or more rumble strips. Each rumble strip comprises at least two interconnected strip sections, each made of a polymeric material. Opposite end edges of the strip sections have respective alternating notches and tabs sized and spaced for engagement with respective tabs and notches on opposite end edges of other of the strip sections to provide a releasable connected joint therebetween. The undersides of the tabs have transverse slots adjacent axial inner ends of the tabs for seated engagement by lower outer cross members extending transversely of the notches adjacent axial outer ends of the notches. The alternating notches and tabs in the respective opposite end edges of the strip sections are dovetailed for dovetailed engagement with one another.
