Highway 50 Retaining Wall

The Highway 50 Retaining Wall Construction Project consists of constructing a 428 foot long retaining wall made up of 58 Cast In Drilled Hole (CIDH) piles ranging from 60 feet to 115 feet in length, 252 ground anchors that will be drilled through the CIDH piles, forming and pouring a barrier slab, installing a new barrier rail, installing timber lagging between the CIDH piles, and repaving of the highway. The retaining wall construction is intended to prevent further landslides in the area which have previously damaged the highway. The project will be constructed in two stages, with the first stage consisting of installing the CIDH piles, and the second stage consisting of installing the ground anchors, timber lagging, barrier slab, and repaving the highway.
