A girder bridge protection device. The girder protection device includes a sacrifice member having girders installed on an upper surface of a bridge seat of an abutment or pier to support a bridge floor, a symmetrical main support member connecting two of the girders and having an elongated tubular configuration, and an auxiliary support member projecting from one surface of a center portion of the main support member in a direction perpendicular to an axial direction of the main support member; and a restraining member secured to the bridge seat of the abutment or pier and having an accommodating section accommodating the auxiliary support member such that the auxiliary support member is separated from the accommodating section in a forward and rearward direction and in a leftward and rightward direction, thereby controlling the behavior of the auxiliary support member.
