coastal route between Falmouth and the Chain of Lagoons – one had to travel into and out of St Marys, both roads being steep grades. The bypass was officially opened on 2 December 1991, though motorists had been using the partially constructed road before its opening. Great care was taken during the construction to protect Aboriginal middens and the general environment. St Helens to Launceston At the Launceston end, the highway is a main road with traffic lights. Out of the city, it becomes an ordinary two-lane road through the mountains. It passes waterfalls and through timber and rainforest country. The portion between Launceston and Scottsdale runs through the Sideling Range. There is a lookout which offers views of Scottsdale and its surrounds.
