In Tasmania, Highway 1 is a Шаблон:Convert long[1] route that connects Hobart to the state's north coast, and to Launceston via a Шаблон:Convert long spur.[2] Highway 1 also exists on the mainland of Australia, linking the state capitals via a circular route around the coastline. All roads within the Highway 1 system are allocated a road route numbered 1, M1, A1, or B1, depending on the state route numbering system. In Tasmania the highway is designated as National Highway 1, though all other routes in the state are alphanumeric.
Highway 1 commences in the Hobart city centre as the Brooker Highway, and travels Шаблон:Convert north on parallel trajectory to the River Derwent until it reaches Granton, where the Highway ends. From this point the Midland Highway becomes Route 1 and travels over the River Derwent and passes through the newly constructed Brighton Bypass before continuing north towards Launceston.[1] A Шаблон:Convert long spur section of Highway 1 travels into the centre of Launceston, first as the continuation of the Midland Highway, and then as a Couplet – northbound on Bathurst Street, and southbound on Wellington Street.[2] South of Launceston, Highway 1 continues west as the Bass Highway to Deloraine, after which it travels north to Devonport, and then west along the northern coast to the route's terminus in Burnie. The Bass Highway, however, continues towards Marrawah on the state's west coast.[1]
