Route Overview:

The Illawarra Highway is an east-west highway connecting the Illawarra coastal plain with the Hume Highway and Southern Highlands. Its most well-known feature is Macquarie Pass, opened in 1898, which is a narrow, steep and winding road ascending the Illawarra Escarpment. The highway has been experiencing a steady increase in heavy vehicle traffic due to the expansion of port facilities at Port Kembla.

The Illawarra Highway began classified life in 1928 as a conglomeration of a number of Main Roads. In the 1950s the importance of the Moss Vale-Albion Park route was recognised and its status was duly upgraded to that of a trunk route. On 3 August 1962 the Department of Main Roads declared this route as State Highway No. 25 and named it Illawarra Highway.

Originally omitted from the National Route marking scheme, the Illawarra Highway was given the National Route 48 shield in 1974.
