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.
Princes Highway:
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 Kogarah and Waterfall in Sydney, and then Kiama near Wollongong through to the Victorian Border. The route is a mix of urban arterial road, dual carriageway and also rural highway.
History:
- Princes Highway:
- 7 June 1926: The Princes Highway comes under a federal and state government £ for £ funding scheme, thus recognising the importance of the highway as major route.
