Jon and the team tackle the first piece of a 2,000-ton TUNNEL BORING MACHINE, the 181-ton MAIN BEARING. With 7-hours to travel 68 kilometers it sounds easy, but not when they’re facing bridges that are as low as their load is high – and they need to try to cross the Brisbane River bridge on the wrong side of the motorway. Meanwhile two new drivers, Kiwis Wayne and Boof, are attempting to prove themselves on Jon’s MegaTrucker testing ground, a 700km contract hauling COAL WAGONS between Brisbane and Rockhampton. But, when faced with an unprecedented amount of road-works, will they be tempted to put their foot down, breaching Jon Kelly’s strict rules on speeding and jeopardizing their chances of becoming fully-fledged MegaTruckers?
