M/A/B1 (Princes Highway (including South Eastern Freeway), Port Wakefield Road and also
Eyre Highway)
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 3 designations:
- M1: this is the designation given to the South Eastern Freeway from Adelaide (Glen Osmond) to Murray Bridge (Tailem Bend)
- A1: this covers several sections of highway 1 including Princes Highway from Vic/SA border to Mount Gambier, Port Wakefield Road from Adelaide to Port Augusta and the Eyre Highway which crosses the Nullabor Plain.
- B1: this is the Princes Highway from Mount Gambier to Tailem Bend.
Princes Highway:
The route from the Vic/SA Border to Tailem Bend was fully sealed by around 1955, when it was given the National Route 1 shield.
Changes along the route since the sealing work include the realignment in Mount Gambier to what is known as the Jubilee Highway, from Commercial Street, in the 70s, and a bypassing of the town of Glencoe in the 80s. In 1998 Transport SA replaced National Route 1 with the B1 and A1 route numbers as part of the switchover to alphanumeric route numbers.
South Eastern Freeway:
The South Eastern Freeway, is South Australia's first ever freeway. It was built in the mid-70s and links Adelaide with Murray Bridge. The freeway replaced a section of the Princes Highway through the Adelaide Hills.
In late 1997, the Adelaide-Crafers Highway was completed which provided a freeway grade road featuring a 600m tunnel linking Glen Osmond to Crafers, replacing the old windy Mt Barker Road.
Port Wakefield Road:
Port Wakefield Road branches off of Main North Road at Gepps Cross in the northern suburbs of Adelaide. The highway is dual-carriageway until Port Wakefield and connects Adelaide to Port Augusta. Various changes have been made to the road over the years including Two Wells and Virginia being bypassed in the mid-60's, and the Crystal Brook bypass during the 90s. Towns and cities along the route include Adelaide, Two Wells, Port Wakefield, Snowtown, Crystal Brook, Port Pirie, Port Germein, Stirling North and Port Augusta.
Eyre Highway:
The completion of the Eyre Highway was celebrated on 29 September 1976 at Wigunda, 172 km east of Eucla on the Nullabor. Present at the ceremony was South Australian Minister for Transport, Mr Geoff Virgo and Highways Commissioner, Keith Johinke.
Named after Edward John Eyre, the Eyre Highway is the primary road link between Western Australia and the eastern states of Australia. Constructed during the World War II, the current route of the highway has not been deviated from significantly during various upgrades to the highway. Towns and localities along the route include Flinders Ranges, Port Augusta, Eyre Peninsula, Poochera, Ceduna, and the Nullarbor Plain.
