Current engineering concerns would be to determine maintenance of the current travel corridor and construction upgrades. The route does contain a variety of road surfaces ranging from asphalt concrete, thin membrane surface (TMS), granular pavements and gravel highway. Insight into current surface texture, traffic volume, traffic speed, percentage of loaded trucks, climate variations, construction costs and time as well as available materials will affect upgrade procedures. The entire route is paved except for a Class 4 gravel highway segment between Nipawin and the Manitoba border. Here the traffic volume declines to 80 and 85 vpd and two checkpoints near the Manitoba border.
