ABSTRACT:
An expansion joint adapted to overlie and sealingly close an expansion gap between roadway bridge sections or the like and comprising an elastomeric membrane having an upstanding arch disposed across the gap. The arch has a corrugated configuration with the corrugations thereof extending laterally across the gap to impart substantial flexibility to the membrane so as to accommodate relative movement of the roadway sections in each of the vertical, longitudinal, and lateral directions. Side rails overlie the side edges of the membrane and anchor the membrane between the road sections.
