Retrieved on 4 September 2013.〕 (formerly the Lower Yarra Freeway) is a major freeway in Melbourne, the busiest urban freeway and the busiest road in Australia, carrying upwards of 200,000 vehicles per day. It links Geelong (via the Princes Freeway) and the Western suburbs to the Melbourne CBD and beyond. It is also a link between Melbourne and the west and linking industrial and residential areas west of the Yarra River with the city and port areas. The iconic West Gate Bridge is a part of the freeway. It is a fully managed freeway and one of the best examples of this in the world, with a complete 'Freeway Management System' that is dynamically linked and adaptive to the entire M1 corridor. This includes the 2008 re-design of a substantial section. Overall, the freeway has between 4-6 lanes in each direction, with a maximum of 12 lanes at one point in its width. ==History== The freeway was originally designated in the 1969 Melbourne Transportation Plan as the F9 Freeway corridor. Construction began on the first section in the late 1960s and was open to traffic by 1971,〔Country Roads Board Victoria. Fifty-eighth Report: for the year ended 30 June 1971. Burwood, Victoria: Brown, Prior, Anderson, 1971. p. 2〕 stretching from the intersection of the Princes Highway and Little Boundary Road in Altona North (later enlarged and named the West Gate Interchange) eastwards to Melbourne/Williamstown Roads just west of the mouth of the Yarra, initially designated with an F-82 shield. At the time, the only way to cross the Yarra west of the CBD was via a ferry crossing, which naturally saw far heavier demands once the Lower Yarra Freeway was officially opened. The West Gate Bridge across the Yarra had started construction not too long before the opening of the freeway and, although delayed, when finally completed in 1978〔Country Roads Board Victoria. 66th Annual Report. 1978-1979. Kew, Victoria: Country Roads Board Victoria, 1979. p. 9〕 allowed the freeway to extend over the river and directly into the CBD's south-western corner (via Rogers and Lorimer Streets). The freeway's name was changed to the West Gate Freeway to commemorate its opening, but the freeway also attracted tolls from anyone using the bridge (between Melbourne/Williamstown Road and Rogers Street) between 16 November 1978 and 29 November 1985.〔(【引用サイトリンク】title=M1 West Gate Freeway )〕 The toll plaza was located on the city side of the bridge where the service stations are now located.〔(【引用サイトリンク】title=Miscellaneous:1977. West Gate Bridge Toll Plaza )〕 National Route 1 - previously designated along Geelong Road (Princes Highway West) and through the CBD via Smithfield and Flemington Roads and King Street - was altered to use the freeway instead and rejoin Kings Way via Rogers, Lorimer and Clarendon Streets. 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「West Gate Freeway」の詳細全文を読む スポンサード リンク
