Western Scheldt Tunnel ((オランダ語:Westerscheldetunnel)) is a tunnel in the Netherlands on highway N62 under the Western Scheldt estuary between Ellewoutsdijk and Terneuzen. It is the longest tunnel for highway traffic in The Netherlands. ==History== The tunnel was built by a consortium of Franki Construct, Heijmans, Royal BAM Group, Philipp Holzmann, TBI Beton- en Waterbouw Voormolen and Wayss & Freytag〔(Structurae database )〕 on behalf of NV Westerscheldetunnel (the Western Scheldt Tunnel Company) 100% ownership by the province of Zeeland. The tunnel was opened on 14 March 2003. Since then the automobile ferry between Flushing (Vlissingen), Breskens, Kruiningen and Perkpolder operated by the Provincial Steamboat Service (Provinciale Stoombootdiensten) in Zeeland has been discontinued. The Western Scheldt Tunnel is a bored tunnel and consists of two tubes which were excavated by a tunnel boring machine. Each tube has room for two driving lanes, but does not have a hard shoulder. Every 250 metres, the two tunnel tubes are connected to each other by lateral connections. Normally the cross-connections are closed and locked. But in an emergency, the doors will automatically be unlocked. The traffic in the left driving lane in the other tunnel will be stopped to allow people to walk safely to the other tunnel. The Western Scheldt Tunnel is diameter, long and has, on the south end, a length of over , a section of the road with an uphill grade of 4.5%.〔 The maximum clearance is . The tunnel reaches its deepest point under the Pas van Terneuzen, below water level. The toll for the tunnel is collected near Borssele for both directions. 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「Western Scheldt Tunnel」の詳細全文を読む スポンサード リンク
