Along the west side of U.S. 2/7, crews will continue removing material including ledge over the next several weeks to facilitate the installation of the retaining wall. This work will include hammering to break up the ledge for removal. This work will be completed under lane closure of the outer southbound travel lane on U.S. 2/7 and lane width reduction of the I-89 southbound offramp.
