A bridge expansion joint assembly includes at least a first expansion module and a second expansion module on opposing bridge structures. The first expansion module includes a first hinge pivotally mounted to a first bridge structure so the first hinge can rotate about a first axis, and a first group of fingers pivotally mounted to the first hinge so the first group of fingers can rotate about a second axis. The second expansion module includes a second hinge pivotally mounted to a second bridge structure so the second hinge can rotate about a third axis, and a second group of fingers mounted, either fixedly or pivotally, to the second hinge. The first group of fingers and the second group of fingers are interdigitated and rest upon a sliding support.
