Förbifart Stockholm (''Stockholm Bypass'') is a series of underground expressway tunnels currently under construction between the Kungens Kurva interchange in the south of Stockholm and the Häggvik interchange north of Stockholm. Most of this bypass; more than 17 out of 21 kilometers, is built underground. The Swedish government decided to permit the construction of the bypass on September 3, 2009, according to the proposal by the Swedish Road Administration. The bypass will become the world's longest tunnel in the proximity of a city. 140 000 vehicles per day are expected to use the bypass. The tunnel reaches at its deepest point 65 meters below sea level and the lake Mälaren. The projected cost for the project is estimated at 27.6 billion (short scale) SEK (2009 value). Construction began in August 2014 but was stopped for political reasons soon after but was restarted in early 2015 and is expected to take ten years to complete. ==History== The highway in the planning stage since 1966, when a regional planning sketch titled ''Greater Stockholm Physical Structure 2000'' ((スウェーデン語:Storstockholm fysisk struktur år 2000)) proposed three concentric circular arcs surround Stockholm to the west.〔City 67, page 8〕 The innermost arc was Brommagrenen, whose on-ramps were put in place already when Essingeleden was under construction. The next bypass to the west was a connection between Essingeleden at Brännkyrka over Ålsten past Bromma airport and northwards, an extent that is reminiscent of Diagonal Ulvsunda. The third, outermost bypass had an extent mostly coinciding with the currently planned Förbifart Stockholm and was called ''Kungshattsleden''. In the Dennispaketet it had the name ''Västerleden''. In 2001, an alternative consisting of a tunnel under Ekerö was included in the plans.〔Stockholms Handelskammare - trafik Stockholm 2001.06.07 s.2〕 The road capacity over the relatively narrow passage between Saltsjön in the east and lake Mälaren in the west (where Stockholm is located) has not been expanded since Essingeleden opened in 1967. Essingeleden was designed with a capacity of 80,000 vehicles per day; today, the load is twice that on a normal weekday.〔Program "Förbifart Stockholm", page 5〕 This makes Essingeleden sensitive to traffic disturbances, with consequent road congestion. The heavy vehicular load also causes severe wear and tear on the road surface, with large needs for reparation as a result.〔 To solve the problem the Road Authority presented in its investigation ''North-South connections in the Stockholm area 2005'' (''Nord-sydliga förbindelser i Stockholmsområdet år 2005'') three alternatives: Förbifart Stockholm, Diagonal Ulvsunda, and a combined alternative; the Road authority recommended the first alternative. The Centre Party, Liberal People's Party, Christian Democrats, Moderate Party, and Social Democratic Party were in 2010 supportive of the road project, while the Green Party and Left Party were opposed to it.〔http://www.socialdemokraterna.se/Webben-for-alla/Landsting/Stockholms-lan/Media/Mars-2008/Forbifart-Stockholm-kan-inte-vanta/〕〔http://www.mp.se/templates/mct_177.aspx?number=181531〕〔http://www.vansterpartiet.se/index.php?option=com_content&view=article&id=2386:foerbifart-stockholm-en-gigantisk-miljoemiss&catid=298:infrastruktur&Itemid=246〕〔http://www.dn.se/sthlm/ja-till-forbifart-stockholm-1.944424〕 Arguments supporting the construction of the bypass are the creation of improved road access, reduction of inefficient travelling time, and reduction the load on central parts of Stockholm due to transit traffic. Arguments against construction cite increased carbon dioxide emissions, the high cost, environmental impact along the construction route, and that traffic problems are not being addressed in a long-term perspective because travellers in the Stockholm region are enticed to continue using private transportation rather than public transportation, and because a high percentage of the present-day traffic on the frequently congested Essingeleden is local traffic to or from central Stockholm, rather than transit traffic. On 19 August 2014, there was a groundbreaking ceremony, led by the minister for infrastructure. However, after the election of September 2014, a new government was elected and they decided on 23 October 2014 to halt the construction (even if contracts with construction companies were signed) for a half-year period in order to debate the project. Soon a decision was made to restart the project, but this political manoeuver delayed the project for half a year. 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「Förbifart Stockholm」の詳細全文を読む スポンサード リンク
