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:
1881: Construction of the Nowra Bridge over the Shoalhaven River.
17 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).
11 July 1928: Princes Highway became a state highway. 2
1936: Construction of deviations between Nowra and Batemans Bay, other deviations in this period include various sites including Tomerong, Stewarts and Luncheon Creeks, Myrtle Gully, Conjola, Ulladulla (East Lynne to Batemans Bay), straightening of highway between Nowra and Batemans Bay, including 22 new concrete bridges in that section.
1939: By the middle of the year, 300 miles (or 50% of the then highway) had been paved with bituminous surface.
1981: Duplication of Nowra Bridge.
16 March 2008: Work started on upgrading Princes Hwy to 4 lanes between Forest Road at South Nowra and Jervis Bay Road at Falls Creek. 3
November 2011: Construction on the upgrade started at South Nowra to provide consistent four lane conditions on the Princes Highway between Bomaderry and Jervis Bay Road. 4
