Goongoongup Bridge is a railway bridge in East Perth, Western Australia which crosses the Swan River and forms part of the Armadale line. It opened on 24 July 1995 as part of the electrification of Perth's suburban railway network.〔"New Perth Bridge Opens" ''Railway Digest'' September 1995 page 16〕 The name is derived from the Nyungar word for the Claisebrook area.〔(【引用サイトリンク】date=24 July 1995 )〕 Goongoongup Bridge replaced the 1932 built timber Bunbury Bridge which was demolished in 1996.〔(【引用サイトリンク】title=Perth's Bridges )〕 It had replaced the original 1893 structure that was damaged by floods.〔 The double-track concrete bridge is 407 metres long and is supported by eight piers. A dual-use pedestrian/cycle pathway is beneath the main deck. A six-lane road bridge Windan Bridge opened in 2000 and is situated parallel and two metres upstream from Goongoongup Bridge. ==Repairs== In 2002, movement of soil on the eastern end of the bridge was detected.〔Stewart, D.P. and McInnes, D.B. The impact of lateral soil displacements on the Goongoonup rail bridge, Perth, 8th ANZ Conference on Geomechanics, Canberra, ACT, Australian Geomechanics Society, 1: pp 345-351 (1999)〕 Displacement of 140 mm on the abutments was measured and engineering reports predicted the displacement would be 300 mm by the end of the century and that the abutment piles would yield in 10 to 20 years. Repair work by the Public Transport Authority commenced in August 2011 and was completed in early 2013.〔(【引用サイトリンク】title=Goongoongup Bridge Works )〕 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「Goongoongup Bridge」の詳細全文を読む スポンサード リンク
