An expansion joint system for bridging a gap between spaced apart structural members and for accommodating transverse movement. The expansion joint system includes a plurality of finger plates carrying a plurality of elongated fingers that are configured to at least partially extend across an expansion joint gap from opposing structural members. The finger plates are pivotably mounted to the underlying structural members to permit pivoting or rotating movement in the transverse direction. A torsion spring is engaged with the pivotable finger plates and provides a restoring force to the finger plate when the finger plate rotates relative to the spring. Also disclosed is an expansion joint including spaced-apart structural members and the expansion joint system installed in the joint. The elongated fingers of the finger plates of the expansion joint system extend at least partially across the expansion joint gap from a first structural member and are interdigitated with elongated fingers extending from a opposing second structural member to provide a surface to traverse the expansion joint gap.
