This was renamed New England Highway, through Queensland on 14 February 1933, and a month later through New South Wales on 14 March 1933, running from Hexham, Maitland, Singleton, Tamworth, Armidale, Glen Innes, Tenterfield, Woodenbong and Beaudesert to Brisbane. In November 1949, a sealed road was opened through Cunninghams Gap, linking south-western Brisbane to Warwick, to eventually supplant the route via Mount Lindesay as the main Brisbane-Sydney traffic route as far south as Tenterfield. As a result, New England Highway was re-routed through Warwick along the route that was then known in Queensland as the Lockyer-Darling Downs Highway on 11 August 1954. Against the wishes of the Beaudesert Shire Council and the Woodenbong Chamber of Commerce, the former alignment of New England Highway from Tenterfield through Beaudesert to Brisbane was re-declared Mount Lindesay Highway, 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. The NSW Department of Main Roads (which had succeeded the New South Wales MRB in 1932), declared the New South Wales section as State Highway 24, from Tenterfield via Legume and Woodenbong to the state border with Queensland. The New South Wales section of Mount Lindesay Highway, which still included unsealed portions, was eventually de-gazetted as a highway by NSW Department of Main Roads on 23 December 1981 due to very low traffic volumes, it was renamed Mount Lindesay Road and re-declared as Main Road 622. This left the Queensland section as the only surviving part of the highway. Within New South Wales, Summerland Way was consequently extended north 9.4km along the alignment of the former highway to meet the Queensland end of the highway at the state border, and the eastern end of Mount Lindesay Road was truncated at the intersection with Summerland Way just east of Woodenbong. 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.
