Disclosed is a bridge expansion joint for connecting upper plates of a bridge in such a way that it enables the upper plates of the bridge to stretch or to be contracted in order to counteract the contraction and expansion of the bridge according to the changes in temperature, which is capable of preventing the accumulation of foreign substances and of easily discharging them to the outside. A pair of lower plates is disposed between one bridge deck section and the other bridge deck section with leaving a predetermined interval. An upper plate is respectively disposed on an upper surface of the lower plate, in which the width of the upper plate in the horizontal direction is smaller than that of the lower plate. A load supporting means is disposed on the upper surface of the upper plate. The load supporting means comprises a pair of link members or a pair of finger members. A reinforced plate is disposed between the load supporting means and the lower plate, in which an inclined plane is respectively provided at both sides of the reinforced plate so that is the reinforced plate has a narrow top and wide bottom-shaped section.
