Project Title & Location
US 12 - Naches River North of Yakima - Stabilize Slopes

Project Description
The area of US 12 along the Lower Naches River, near the 16th Avenue interchange, suffers from repetitive bank erosion and slope failures. Emergency work has been performed in this area four times since 1999. This project will correct this chronic environmental deficiency by moving the Naches River channel away from US 12, and construct a bio-engineered structure in the river to reduce future problems and protect the roadway and environment.
