General Information:

Highway 1 runs right around Australia, however with the introduction of alphanumeric routes, highway 1 takes on all different identifications depending on its importance and road design.

In South Australia, it's numbered with several designations:

• Princes Highway (A1, B1, NH-A1, NH-M1) (Includes Jubilee Hwy and South Eastern Fwy):

The Princes Highway links Adelaide, Melbourne and Sydney. The highway was first proclaimed from Sydney to Melbourne in the 1920s, it was later extended through western Victoria and eventually to Adelaide.

Towns along this section of Highway include Mount Gambier, Millicent, Kingston SE, Meningie, Tailem Bend, Murray Bridge, Nairne, Mount Barker and Adelaide. The route varies from 2 lane rural highway standard to full freeway standard and includes the Adelaide-Crafers Freeway which features twin 600 metre tunnels.
