General Information:
M1 / A1 is the principal coastal route through New South Wales, and forms part of the circumferential route around Australia.
The route varies greatly along its length and includes sections of rural highway, urban arterial road, divided rural highway and also motorway. The route also features several tunnels, located in the inner east, inner south and lower northern suburbs of Sydney and at Yelgun and Tweed Heads, at the northern end of the route in NSW. The route passes through forest, rural, residential, commercial and industrial areas.
The Princes Highway was formed from a string of roads linking Sydney to the Illawarra, and then forming a coastal route to Melbourne and into South Australia. The section covered by A1 is in 2 pieces - between Rockdale and Waterfall in Sydney, and then Yallah near Wollongong through to the Victorian Border. The route is a mix of urban arterial road, dual carriageway and also rural highway.
History:
- 7 June 1926: The Princes Highway comes under a federal and state government £ for £ funding scheme, thus recognizing the importance of the highway as major route.
- August 1920: Official opening of Princes Highway performed at Warragul in Victoria. The formation of the Princes Highway is from existing roads being renamed, after the visit to Australia in 1920 of the Prince of Wales (later to become King Edward VIII, and after abdicating, the Duke of Windsor).
- 1 July 1928: Princes Highway became a state highway. 2
- 1929: Construction of Tom Uglys Bridge. 3
- 1939: By the middle of the year, 300 miles (or 50% of the then highway) had been paved with bitumous surface.
- 17 October 1987: Duplication of Tom Uglys Bridge complete. Southbound traffic assigned to the new bridge, and the old bridge was assigned to northbound traffic. 3
