The Hume Highway, inclusive of the sections now known as the Hume Freeway and Hume Motorway, is one of Australia's major inter-city highways, running for 807 kilometres (500 mi) between Melbourne and Sydney. Upgrading of the entire route to dual carriageway was completed on 7 August 2013.
The road is called the Hume Freeway in Victoria, the Hume Motorway between and , New South Wales, and the Hume Highway elsewhere in New South Wales. 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 as well as serving Albury-Wodonga and Canberra.
The main alternative route between Sydney and Melbourne is the Princes Highway/Princes Freeway/Princes Motorway route (A1/M1) which follows the coast for most of its length. Other inland alternate routes include the Olympic Highway route (A41) between Albury and Sydney via Cowra and Bathurst, and also the Federal Highway / Monaro Highway route (M23/A23/B23) via Canberra which links with the Hume Highway near Goulburn and the Princes Highway in East Gippsland.
In NSW during 2013, the National Highway shield, National Highway 31, was replaced with a standard alphanumeric route number, the M31 south of Prestons (along with the A22 east of Liverpool into the Sydney CBD and the A28 for a short length through Liverpool). This re-numbering for the first time in over 20 years created one continuously signed route along the Hume Highway, having already been signed the M31 in Victoria during the 1990s. During 2013 the route between Berrima and Prestons was also renamed the Hume Motorway.
