To address the problem, sound abatement wall to reduce highway noise for homes along the interstate were custom designed and installed. The individual panels averaged 6’H x 24’L and posts were spaced at 25’ on center and averaged 12’ tall. Both panels and posts were manufactured with an ashlar stone form-liner on each side.
