abstract:The South Eastern Freeway (now 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.
