Abstract
A roadway with a noise protecting assembly for controlling sound emanating from the roadway. The assembly comprises a plurality of walls having a width disposed vertically above the roadway and a length disposed in a direction parallel to the center line of the roadway. The walls are laterally spaced with respect to each other across the width of a frame structure thereby forming intervals therebetween. The assembly is effective to prevent the direct path of sound from a source of noise on the roadway to objects in the vicinity of the roadway which is the source of the noise.
