This is a list of roads designated A6.
The Midland Highway is one of Tasmania's major inter-city highways, running for 176 kilometres (109 mi) between Hobart and Launceston. It is part of the AusLink National Network and is a vital link for road freight to transport goods to and from the two cities. It represents a major north–south transportation corridor in Tasmania and has the route 1 designation as part of the National Highway. The highway consists of various traffic lane arrangements, the most common being two lanes – one in each direction, with overtaking options and at-grade intersections. At both the Launceston and Hobart sections of the highway there are small portions of grade-separated dual carriageway.
The Brooker Highway is a highway in the State of Tasmania, Australia. As one of Hobart's 3 major radials, the highway connects traffic from the Hobart city centre with the northern suburbs and is the major road connection to the cities and towns of Northern Tasmania. With an AADT of 48,000, the highway is one of the busiest in Tasmania. The Brooker Highway has recently been declared part of the National Highway.
The Kingston Bypass is a A$41 million, 2.8-kilometre-long (1.7 mi) highway bypassing the southern Hobart community of Kingston, Tasmania. The proposal of a bypass was originally published in the Hobart Area Transportation Study during 1965. The bypass was completed in 2011, after the need to such a road was realised several years earlier when the Channel Highway reached an 18,000 AADT. Construction of the Bypass was made possible by an A$15 million pledge for the project, made by the Australian Labor Party during the 2007 federal election campaign. During construction total cost of the bypass blew out from the original estimate of $30 million to over $41 million.
The Huon Highway is an 87-kilometre (54 mi) highway in southern Tasmania, Australia. The highway forms part of the A6 and connects Hobart with the southern parts of Tasmania. The original Huon Highway was a twisty two-lane road skirting around Mount Wellington, but that section of the highway was bypassed in stages when the Southern Outlet was completed in 1968. This provided a more direct, and higher traffic-capacity, route between Hobart and the Huon Valley. A few sections of the old highway remain, all within the Huon Valley, and have been upgraded.
The Kingston Interchange is a hybrid four way interchange incorporating a roundabout and elements of a trumpet interchange. It connects the Southern Outlet with the Huon Highway and the Channel Highway at Kingston, within the greater area of Hobart, Tasmania.
The Southern Outlet is a major highway in the Tasmanian capital of Hobart and acts as one of the city's 3 major radial highways, connecting traffic from the Hobart city centre with commuters from the southern suburbs as well as intrastate traffic from the south of the state. It is one of the busier commuter highways in Hobart, handling in excess of 31,000 traffic movements each day.
The Hobart Bypass is a proposed concept to bypass the Central Business District of Hobart, Tasmania. Currently, through traffic travels from the Tasman/Brooker Highways down the one-way Davey/Macquarie couplet to the Southern Outlet. As well as traffic concerns, there is also a call to build the bypass on the grounds that the current traffic arrangement cuts the central business district off from Hobart's waterfront.
