The high-performance buffering bridge guardrail comprises a plurality of stand columns and a plurality of cross beams, connecting bolts are arranged on the stand columns in a penetrating mode, one ends of the connecting bolts penetrate into the cross beams, sliding grooves are formed in the sides, facing the stand columns, of the cross beams, sliding parts in sliding fit with the sliding grooves are arranged in the cross beams, and the connecting bolts stretch into the sliding grooves and penetrate through the sliding parts. The stand column and the cross beam are arranged to be of the slidable connecting structure and are pressed through the connecting bolt, so that relative positioning is achieved, when the cross beam is impacted by an out-of-control vehicle, the cross beam and the stand column slide relatively, and the cross beam moves towards the impact position; therefore, the total number of the cross beams between the stand columns on the two sides of the collision position is increased, the local defo
