Old Highway 97 Road Repair

Aspect provided geologic and geotechnical engineering support for road repairs and subgrade improvements on 1.5-miles of Old Highway 97 near Brewster. We completed subsurface explorations, geotechnical engineering analyses, and pavement design alternatives including multiple subgrade improvement strategies. We provided cost-effective repairs tailored to individual problem areas while meeting WSDOT standards and local agency guidelines to fulfill funding requirements. We prepared a full geotechnical report along with design-level plans, specifications, and cost estimates for the proposed improvements.
