of the colony at Sydney and of the expansion of white settlement into western NSW. The road symbolises the occupation of the country and Governor Macquarie's aspirations for the eventual opening of the interior to European settlement after the discovery of the Western plains by G. W. Evans in 1814. In this respect the 1814-1815 Cox's Road has considerable symbolic significance as an official public work which laid the foundations for future development. Cox's Road is linked with the foundation of Bathurst, the first inland settlement in NSW, which was proclaimed by Governor Macquarie on 7 May 1815 after his journey along the road. The place has a strong or special association with a person, or group of persons, of importance of cultural or natural history of New South Wales's history. The surviving remnants of Cox's Road have state significance for their close association with Governor Lachlan Macquarie who commissioned the building of the road into the interior, and with the magistrate and ex-army officer Captain William Cox, who supervised the building of the road. The road is also associated with the convicts who laboured on the road to obtain their liberty, and with the officers and men who assisted Cox such as Thomas Hobby, Richard Lewis, John Tighe and Samuel Ayres. The crossing of the Blue Mountains, the surveying of a route to Bathurst and the building of Cox's Road were significant events in the period of Macquarie's governorship. Governor Macquarie's view of the importance of the road is demonstrated by his reports to Earl Bathurst, the British Secretary of State for War and the Colonies, and by his journey to the Bathurst Plains immediately after its construction, where he proclaimed the site for the Bathurst township. William Cox's achievement using a small group of convict men in a short period of time and with no loss of life caused by road-making or other substantial difficulties, was reflective of his reputation as a more humane employer and magistrate than many of his contemporaries. The leadership qualities, vision and skill he showed constructing the road would also be evident in later government contracts won by Cox for other public works. The place is important in demonstrating aesthetic characteristics and/or a high degree of creative or technical achievement in New South Wales. The surviving precincts of Cox's Road have state technical significance for their ability to demonstrate simple, pre 1820s road
