Aboriginal stone tools have also been found on the banks of Towrang Creek, indicating that this was a route well-travelled long before Hamilton Hume came this way in 1824. There is also a rest area on the eastern side of the highway, where a well-preserved bridge dating from 1839 (possibly designed by David Lennox) and a 1960s concrete box culvert can be viewed. Goulburn After the cities of Liverpool and Campbelltown, Goulburn is the first major rural city along Hume Highway from Sydney. It is the centre of a rich agricultural area specialising in fine wool production. From this area comes some of the world's finest wool. Therefore, the city has a monument called The Big Merino near the service station. Goulburn was bypassed on 5 December 1992 and the main street (Auburn Street) is quieter, but still busy during Saturday morning shopping. Picturesque Belmore Park is located midway along Auburn Street. A number of architecturally and historically significant buildings are located near Belmore Park, including the courthouse, the post office and the railway station. Also in central Goulburn are two cathedrals, both of architectural note. A number of old houses and hotels are located near the railway station on Sloane Street. Gunning Gunning's 19th century main street was built very wide, for the time of horse and bullock-drawn wagons. This served the town well when the main highway between Sydney and Melbourne carried cars and trucks through the town. This ceased when the bypass was completed on 5 April 1993. The town is now much quieter, and it has been able to resume a more rural pace of life. It has developed something of an industry in providing bed and breakfast accommodation. The recently built Gunning Wind Farm is located beside the highway, with its wind turbines providing a distinctive landmark. The former route of the highway which passed over the Cullerin Ranges is still in use between Bredalbane and Gunning, now known as Cullerin Road. Yass Yass has an historic main street, with well-preserved 19th century verandah-post pubs (mostly converted to other uses). It is popular with tourists, some from Canberra and others taking a break from the highway. Hamilton Hume's farm Cooma Cottage is located east of Yass, close to the intersection of the former routes of the Hume and Barton Highways. He lived there until his death in 1873. The Yass Bypass opened on 25 July
