The South Eastern Freeway (previously signposted as Princes Highway) is a 66 kilometre four-lane divided carriageway road in South Australia linking the Adelaide-Crafers Highway to the Princes Highway at the Swanport Bridge, a one kilometre long bridge over the River Murray, near Murray Bridge. The Adelaide-Crafers Highway and South Eastern Freeway are seamlessly connected with minimal signage to distinguish them - as a result they are generally considered by South Australians to be a single road, usually referred to simply as the Freeway, as it was the first freeway in South Australia, and is still the longest. It is a part of the National Highway network linking Adelaide to Melbourne and signed as National Highway M1. The three roads mentioned above constitute part of the primary road link between the state capital cities of Adelaide and Melbourne - the other components are the Dukes Highway and Western Highway.


Prior to the initial construction of the freeway in the 1960s, all inbound and outbound road traffic to south-eastern South Australia and to Victoria had to travel on a two-lane highway originally built in the early part of the 20th century. With growth in Adelaide's population issues of congestion and safety mandated reconstruction. Studies began in 1962 for a freeway commencing from Crafers, that endpoint selected arguably due to the massive expenditure incurred with the precedent upgrade of the Mount Barker Road.

Road construction began in 1965 from Crafers and the first stage of eastbound traffic lanes were opened in 1967, the first westbound section in 1969. The freeway was opened in stages as construction progressed. The final section bypassing the town of Murray Bridge and connecting to the new Swanport Bridge over the River Murray opened in 1979, replacing the historic bridge in the town for through traffic.

The opening of the freeway resulted in the less direct Bridgewater railway line losing patronage and eventually closing to passengers in 1987.

South Eastern Freeway from Mount Barker Summit

An additional exit was built at Monarto around 1999 to service an expanding commercial zone and Monarto Zoo in the area.[1] Another exit was announced in 2014 at Bald Hills Road 4 km southeast of the Mount Barker interchange to service growing housing estates in southern Mount Barker and Nairne.[2] The new interchange is expected to be completed by mid-2016.[3] The contract was announced on 1 April 2015 that Bardavcol would commence construction in May 2015, with the interchange including entry and exit ramps in both directions opening in mid-2016. The $27M project will be funded $16M by the Australian government, $8M from South Australia and $3M from Mount Barker district council.[4]

The Freeway bypasses many towns previously along the Princes Highway including


The Adelaide end of the South Eastern Freeway flows seamlessly into the Adelaide-Crafers Highway, which replaced a narrower road contoured to the Adelaide Hills in 2000.

The southeastern end of the freeway, near Murray Bridge feeds onto the Swanport Bridge, a two-lane one kilometre long bridge over the River Murray, where it joins the Princes Highway, a dual-carriageway highway to Tailem Bend. At this point, Highway 1 becomes a two-laned, two-way scenic route which passes the coastal towns of South Australia and Victoria. The National Highway continues to Melbourne as the Dukes Highway (A8) from Tailem Bend to the Victorian border and beyond as the Western Highway.
