description The utility model belongs to the technical field of noise reduction barriers, and particularly relates to a multilayer road and bridge construction noise reduction barrier which comprises a barrier plate body. The side end of the barrier plate body is fixedly connected with a plurality of groups of sound guide plates; a plurality of groups of sound guide holes are formed in the barrier plate body; one side of the sound guide hole is fixedly connected with a sound guide plate; diffusion of noise can be reduced through the barrier plate body, the sound guide plate can guide the noise into the sound guide holes, part of the noise can be absorbed by the sound absorption cotton blocks, part of the noise can flow into the barrier plate body from the position between the two sets of sound absorption cotton blocks, the sound guide cotton blocks can guide the noise to the two ends to flow towards the sound absorption plate, and the sound absorption plate is made of sound absorption plate materials. Noise can be absorb
