An example of PND’s unique design experience is the $45 million Delong Mountain Road Transportation System constructed by Cominco, Alaska. PND was responsible for the design of 50 miles of new road, 10 bridges, 12 major culvert batteries, over 400 cross-drainage culverts, material source access roads, and material source mining plans. During the past four years, PND has been responsible for over 28 forest road design projects totaling over $6 million in construction for the USDA Forest Service, Region 6.
