Description of Project: The existing Williams Fork Dam Access Road runs to the west of Williams Fork Dam and Reservoir. A discrete portion of this roadway, along the left abutment, has exhibited deterioration due to subgrade material loss along a cut/fill portion of the roadway. To inhibit future material loss and allow full access of the roadway, a segmental block gravity retaining wall will be constructed. The proposed gravity wall improvements consist of removing the fill material along the slope adjacent to the roadway to competent rock and constructing a segmental block gravity retaining wall at the base of the slope excavation. The proposed gravity wall consists of 41-inch Redi-Rock Ledgestone blocks. A low strength backfill concrete and granular fill will be placed below the proposed roadway and used to fill between the gravity wall and adjacent rock slope. The low strength concrete backfill was selected to limit earth and surcharge lateral stresses from acting on the wall and will be placed in two lifts. In addition, construction includes the installation of drainage pipe, concrete backfill material, bollards, final grading, and reinforcement appurtenances.
