In civil engineering , a reverse curve (or "S" curve ) is a section of the horizontal alignment of a highway or rail route in which a curve to the left or right is followed immediately by a curve in the opposite direction.
14-754: The Eastern Ring Road is a proposed Link between the South Arm Highway and the East Derwent Highway , within the greater area of Hobart , Tasmania .

56-416: The Tasman Highway, to the head of Kangaroo Bay, across the second beach and along through wirksworth, and to Rokeby . Some land was acquired but construction of the road never began. The Freeway was deemed to be unrealistic in that it was too expensive and would have come in close proximity to Schools and other vital services. The concept of providing a major arterial road to Howrah was revisited with
70-563: The boundary of Warrane and Mornington . The road continues north from the interchange as Flagstaff Gully Link to Flagstaff Gully , while immediately to the south is a roundabout with Cambridge Road, which carries the C329 road route towards Mornington . Only 150 metres (490 ft) south of the roundabout is a T junction with Mornington Road, for access to the Mornington Business Estate. The highway continues south past
84-547: The earthworks were completed in the first stage, the final one km (0.62 mi) proceeded as single carriageway to the old South Arm Highway alignment. Completion of the bypass replaced Clarence Street as the major trunk road connecting South Arm and Hobart which passed through Bellerive and Rosny . The final section of the bypass was completed in 2009, with the duplication of the South Arm Highway to Oceana Drive. Originally planned to be fully grade-separated ,
98-594: The eastern shore of the River Derwent in Tasmania , Australia . The highway is a major trunk road that carries heavy commuter traffic south from the Eastern Outlet to Howrah and Rokeby . As one of the Tasman Highway's principle Feeders and one of the eastern shore's major transport corridors, The South Arm Highway facilitates the movement of traffic between the suburbs and satellite communities to
112-457: The existing Flagstaff Gully Road. The council argued that, as this new road will be linking 2 state highways, it should be a state government responsibility. However, the state government saw it as a council issue.

140-526: The industrial area, and then curves to the south-east around the Waverley Flora Park. After entering the residential suburb of Howrah , South Arm Highway continues south-east to intersect Shoreline Drive at a large roundabout. Beyond this intersection, the highway passes through a reverse curve to reach its southern terminus at Oceana Drive. Rockeby Road continues on from the highway, as single-carriageway road, towards South Arm . The highway
154-474: The release of the "Hobart Transport Revision" several years later. This new proposal entailed construction of a major road in an undeveloped corridor, bypassing Bellerive .

In 2007 the Clarence City Council backed the proposal to extend
196-425: Was first investigated in 1995 when Ratio Consultants did a study on the proposed link. They considered four options for the link, the most popular choice would connect to the East Derwent Highway between Geilston Bay and Risdon Vale . Ratio concluded that constructing any of the options would most likely produce an unacceptable level of visual landscape, ecological, heritage and water quality impacts. In 2005 during
