".. the best surviving examples of large-scale convict transportation and the colonial expansion of European powers through the presence and labour of convicts."
The road was an engineering triumph, with some sections constructed to a notably high standard. Unfortunately, it was not an unqualified success in practical terms. Apart from the steep grades, there was a lack of water and horse feed along the route. For these reasons it quickly fell into disuse with the development of alternative means of getting to the Hunter Valley, such as steamships and newer roads. Much of the road fell into total disuse while other parts were absorbed into the urban and rural road network.
The Great North Road survives to this day, but different parts are preserved in very different ways. Much of it is under bitumen and concrete, either as suburban streets or rural backroads, while some is preserved in national parks and protected from vehicular traffic. Slight evidence of its past, such as bypassed bridgeworks or even convict rock carvings, survives within the Sydney metropolitan area; by contrast large stretches remain in original condition north of the Hawkesbury River. The first few kilometres, from Five Dock to the Parramatta River, pass through a local shopping strip and suburban area. The historic name is retained for this section, the only reason anyone would think twice about this unremarkable piece of suburban road. The road then recommences at the Baulkham Hills intersection with Windsor Road. Known as Old Northern Road, and Tourist Drive 15, it winds up past the suburbs of Castle Hill, Glenhaven, Dural, before continuing north as a two-lane undivided road. Old Northern Road terminates at Wiseman's Ferry. At Bucketty, it is once again renamed the Great North Road. Two sections of the original route: the Devine's Hill to Mount Manning section and the Mount Manning to Wollombi section are listed on the New South Wales Heritage Register.
Preservation
In 1990, the local communities of Bucketty and Wollombi established the 'Convict Trail Project', aiming to restore, maintain and promote the road as a museum of convict engineering. Original sections of the road which are on view have provided valuable insight into early road construction techniques in the colony of New South Wales, and how English road-building technology of the time was imported and adapted. Prisoners from facilities managed by Corrective Services NSW have been involved with maintenance.
In July 2010, at the 34th session of the UNESCOWorld Heritage Committee, the Great North Road and ten other Australian sites with a significant association with convict transportation were inscribed as a group on the World Heritage List as the Australian Convict Sites. The listing explains that the 11 sites present "the best surviving examples of large-scale convict transportation and the colonial expansion of European powers through the presence and labour of convicts". Of the 11 sites the Hyde Park Barracks, Cockatoo Island, Old Government House at Parramatta are also within the Sydney region. As part of the works to bring about public engagement with the UNESCO World Heritage Listed 'Old Great North Road' that is managed by the New South Wales National Parks & Wildlife Service, a 'living history' theatre production was commissioned to tell some of the stories in-situ on Devine's Hill in Dharug National Park, Wiseman's Ferry, along the living remnants of The Road itself. 'Convict Footprints on the Old Great North Road' is a heart-touching, at times funny, at times deeply sad journey with the men and women that built The Road along the very cobbles they themselves walked.
