The invention discloses an expressway acoustic barrier which comprises a front plate, a rear plate and a middle partition plate. The front plate and the rear plate are galvanized plates. The middle partition plate is in a honeycomb shape. Four to ten rows of horizontal sound absorption holes are formed in the front plate. Vertically-protruding square reinforcing ribs are arranged between the sound absorption holes. Sound insulation felt is arranged between the front plate and the middle partition plate. An aerated concrete plate is arranged between the rear plate and the middle partition plate. The thickness of the sound insulation felt is different from that of the aerated concrete plate. The expressway acoustic barrier is attractive in appearance and convenient to install, the sound absorption effect can be achieved through the front plate with the holes and the sound insulation felt between the front plate and the middle partition plate, the sound insulation effect is achieved through the middle honeycomb-shaped partition plate and the aerated concrete plate, the strength can be increased through the middle partition plate, and the space partitioning and double-layer sound insulation effects are achieved; due to the fact that the thickness of the sound insulation felt is different from that of the aerated concrete plate, the plates of different thicknesses are overlaid, sound wave matching troughs are mutually staggered, and each matching trough is shallow, so that the sound insulation effect is good.
