The Mount Lindesay Highway is an Australian national highway located in Queensland, also known as National Route 13.〔(Queensland Government - Department of Transport and Main Roads - Maps )〕 The highway runs southwest from Brisbane, where it leaves Ipswich Road in the suburb of Moorooka (as Beaudesert Road to the Logan Motorway), to the Queensland – New South Wales border and is approximately in length. ==Location and route== Until 1954, the route was part of the New England Highway between Sydney and Brisbane. However, the opening of the road from Tenterfield to Wallangarra created a better road for the New England Highway and this route was renamed the Mount Lindesay Highway. Until 1977, the Mount Lindesay Highway as a named road extended beyond the Queensland – New South Wales border to Tenterfield but the New South Wales section of the road, which still includes some unpaved portions, was decommissioned as a highway by the New South Wales Government due to very low traffic volumes. Approximately south of the Queensland – New South Wales border the decommissioned part of the Mount Lindesay Highway intersects the northern end of the Summerland Way, known as New South Wales route B91, which runs south to Casino and then on to Grafton. South of Rathdowney the highway becomes very winding as it climbs the McPherson Range. However it is a scenic road, and connects to the northern end of the Lions Road, a scenic drive between Innisplain and the Summerland Way just south of Roseberry, passing Mount Chinghee National Park and Border Ranges National Park on the way. The highway is named after Mount Lindesay, the residue of a solidified magma core, that is part of the Mount Warning volcanic area and is situated in the western extreme of Border Ranges National Park. Until the 1950s it formed part of the main traffic route between Brisbane and Sydney. The coastal route (now the Pacific Highway) was not favoured due to the large number of ferry crossings of the wide coastal rivers, the frequency and severity of flooding of these rivers and the consequent poor state of much of the road for extended periods, and its steep, winding nature as it crossed the intermediate hills between each river valley. In the mid-1950s a sealed road was constructed west from Boonah through Cunninghams Gap to Warwick, and this supplanted the Mount Lindesay Highway as the main Brisbane – Sydney traffic route as far south as Tenterfield. This in turn has since the 1980s been supplanted by the Pacific Highway as the major Brisbane – Sydney route, as a result of extensive upgrading and deviations of the Pacific Highway. Between 2007 and 2009 of the highway in the Logan City local government area was upgraded. As well as providing dual carriageways, the work included building service roads so that local traffic does not have to travel on the main carriageways, thereby reducing congestion. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mount Lindesay Highway」の詳細全文を読む スポンサード リンク
