An expansion joint seal for closing a gap between spaced-apart structural members has an elongated body including longitudinal side edges, an upper corrugated treadway surface, a lower undersurface, and an internal web structure including a plurality of laterally spaced vertically disposed webs each having an upper pair of cross-bars extending upwardly and outwardly therefrom and connected to the upper treadway and a lower pair of cross-bars extending downwardly and outwardly therefrom. An additional lower cross-bar extends from each side edge downwardly and inwardly to a pair of curved surfaces, and a vertically disposed web extends between the juncture of the curved surfaces and the centermost cross-bars. An upper cross-bar extends upwardly and inwardly from each side edge to the upper treadway surface.
