The Forth Estuary Transport Authority (FETA) is the authority responsible for the maintenance of the Forth Road Bridge over the Firth of Forth in eastern central Scotland. FETA was created in 2001 by the Transport (Scotland) Act 2001 - to replace the Forth Road Bridge Joint Board. The board of FETA has ten members, allocated as follows: * four to the City of Edinburgh * four to Fife Council * one to the Perth and Kinross Council * one to West Lothian Council ==History== The Forth Estuary Transport Authority was formed in 2001, with a wider remit than the Forth Road Bridge Joint Board it replaced. It was able to fund road and public transport improvements to aide crossing the Firth of Forth, and its new powers permitted it to include the use of routes other than the Forth Road Bridge, such as using the Firth of Forth itself for hovercraft services between Fife and Lothian. The Forth Road Bridge underwent a comprehensive structural survey between 2003 and 2005 after suspension bridges of similar design and age in the United States were found to be suffering from corrosion in their main suspension cables. The survey results showed significant corrosion and an accompanying loss in strength of between 8 and 10% in the cables on the Forth Bridge. The rate of corrosion and weakening of the main cables would have required the bridge to close to HGV traffic some time around 2014 and then close to all traffic by 2019, so plans were drawn up to build a replacement crossing, to run parallel to the existing road bridge between Lothian and Fife. Dehumidification equipment was installed to remove moisture from the inside of the main suspension cables, in an attempt to slow or halt the corrosion, but with no guarantee of success, the Forth Estuary Transport Authority and Scottish Government were left with no option but to plan the construction of a new crossing. 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「Forth Estuary Transport Authority」の詳細全文を読む スポンサード リンク
