General Information:
B73 is an important route linking the New South Wales Southern Highlands with the coastal regions of the Illawarra and Shoalhaven.
The route services residential, commercial and rural areas and connects with many tourist attractions such as Corbett Gardens in Bowral for the annual tulip festival, Fitzroy Falls and Kangaroo Valley. The road passes through significant conversation areas and makes a steep descent down several mountain passes including Cambewarra Mountain and Barrengarry Mountain.
Another feature of the route is Hampden Bridge at Kangaroo Valley, which is a suspension bridge built between 1895 and 1898. The bridge is the second major suspension bridge in NSW, and now the only surviving timber decked vehicular suspension bridge constructed in the nineteenth century. The bridge has the Kangaroo River running beneath it. The main span length is 77 metres, sandstone tower height of 16.8 metres and height above water also of 16.8 metres. The main cables of the bridge consist on each side of fourteen 36 mm diameter wire ropes, each with a specified tensile strength of 79.6 tonnes. The bridge is signposted for a maximum truck load of 42.5 tonnes, with no more than one truck to be on the bridge at a time, and is lanemarked to only provide a single lane. Hampden Bridge was built to replace the timber truss bridge of 1875 to 1879, which was in a state of decay by 1893. 2
