The Lyttelton road tunnel runs beneath the Port Hills to the south of the New Zealand city of Christchurch and links the city with its seaport, Lyttelton. It opened in 1964 and carries just over 10,000 vehicles per day as part of State Highway 74.〔 At , it is the longest road tunnel in New Zealand,〔(【引用サイトリンク】url= http://www.nzta.govt.nz/network/maintaining/bridges-structures.html )〕 but will be superseded in 2017 by the Waterview Tunnels. While the tunnel itself was not damaged due to the February 2011 Christchurch earthquake, the Heathcote tunnel canopy was destroyed. The nearby Tunnel Control Building — a Category I heritage building — suffered significant damage and was closed, before finally being demolished in 2013. Construction of a new control building was completed in 2014.〔(【引用サイトリンク】url= http://www.nzta.govt.nz/about/media/releases/3532/news.html )〕 ==History== Lyttelton and Christchurch have been linked by a rail tunnel since 1867.〔(【引用サイトリンク】url= http://christchurchcitylibraries.com/Heritage/EarlyChristchurch/LytteltonTunnel.asp )〕 However road transport was restricted to routes over the Port Hills, either via Evans Pass or the Sign of the Kiwi. Construction of the road tunnel started in 1962 and was completed in 1964 at a cost of £2.7 million.〔 When it officially opened on 27 February 1964 it was hailed by the local community as "the new gateway for the Port to the Plains" and a significant development in the history of the region.〔 A 20 cent toll levied to use the tunnel was abolished by the Christchurch-Lyttelton Road Tunnel Authority Dissolution Act 1978, which became effective on 1 April 1979. The original Lyttelton Road Tunnel Administration Building, designed by Christchurch architect Peter Beaven, was a Category I listed heritage building and one of the youngest buildings recognised by the trust. Following its demolition as a result of damage sustained in the February 2011 Christchurch earthquake, a new control building, constructed to 180% of the Building Code to withstand future earthquakes, was completed in 2014 at a cost of $1.5 million.〔 , the tunnel has an AADT (average daily traffic volume) of 10,755 vehicles/day, of which 12.3% are heavy goods vehicles. Cyclists are not allowed to use the tunnel, although for many years they were allowed to pass through on one day a year. For example, the 2001 tunnel ride was held in conjunction with the 3rd NZ Cycling Conference.〔(【引用サイトリンク】url= http://archived.ccc.govt.nz/recreation/cycling/conference/2001/ )〕 However, since 2007 Christchurch buses have been equipped with bicycle carriers to allow cyclists' access between Heathcote and Lyttelton. 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「Lyttelton road tunnel」の詳細全文を読む スポンサード リンク
