It carries traffic over the Adelaide Hills between Adelaide and the River Murray, near Murray Bridge, connecting via the Swanport Bridge to the Dukes Highway which is the main road route to Victoria. It is often referred to by South Australians simply as ''the Freeway'', as it was the first freeway in South Australia, and is still the longest, and the only one with "Freeway" in its name rather than "Expressway" or "Highway". It is a part of the National Highway network linking the state capital cities Adelaide to Melbourne and signed as National Highway M1. The South Eastern Freeway includes 500-metre-long twin-tube tunnels (the Heysen Tunnels) in the descent towards Adelaide, the first of their kind on the National Highway. It is designated as the M1. ==Structure== The South Eastern Freeway features 6 lanes of traffic, arrester beds and concrete median barriers, with street lighting between Glen Osmond and Crafers. The remainder of the length to the Swanport Bridge is dual carriageways with two lanes in each direction. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「South Eastern Freeway」の詳細全文を読む スポンサード リンク
