The Northern Frontier

On their first runs of the new season, Lisa is forced to stop when the unrelenting road knocks her engine apart, and Todd attempts an ambitious bush fix to muscle his load back onto the trailer. Meanwhile, rookie Scooter gets creative to squeeze his wide load down the narrow winter roads. Further west, Shaun checks ice thickness on his most important winter route - only to discover it's too thin to support his truck, forcing him to seek solutions with the crew building the ice road.
