Project location

US 18 retaining wall, Helenville - Jefferson County​

Project overview

The retaining wall on US 18 is tipping toward the sidewalk and is in need of repair. The work on this project includes removing the coping from the retaining wall that spans the entire length of the wall. Excavation behind the wall will occur in locations where the wall panels are tipping toward the sidewalk. The select wall panels are going to be removed and re-set so they are in line with the rest of the wall. The area behind the wall will then be backfilled and the new coping will be cast in place along the entire length of the wall. The railing will be removed as well and re-set in its existing location.
