Session 1, Track 3

Steel Dowel/Reinforced Concrete Retaining Wall Stabilizing System

A 479.5-foot long retaining wall system consisting of two parallel rows of steel dowels socketed into bedrock and topped with a reinforced concrete cap was constructed to stabilize a roadway that has been afflicted by chronic landslide movement for over the last 50 plus years. The dowel system allowed for the majority of construction work to be performed from the roadway/bench elevation without the need for the placement of equipment on the steep, slide-prone downhill slope. Additionally, the concrete cap used to tie the two rows of dowels together not only served to stiffen the dowel system but was also designed to function as a new sidewalk and roadway curb.
