Mooney Mooney Creek Bridge, popularly known as the Mooney Mooney Bridge, is a twin cantilever bridge that spans Mooney Mooney Creek in Brisbane Water National Park on the Central Coast of New South Wales as part of the Pacific Motorway. It is the highest road bridge in Australia as measured from the road bed to the water below.〔(【引用サイトリンク】 work=History on the Hawksbury River )〕 It was opened in December 1986 and is maintained by NSW Roads and Maritime Services.〔. Retrieved on 13 February 2007.〕 The Pacific Motorway is the main road link between Sydney, the Central Coast and the Hunter Region. The only other road that links all three regions is the Pacific Highway which from Cowan to Kariong follows a scenic winding route.〔(【引用サイトリンク】 work=Ozroads: NSW State Route 83 )〕 ==Design== Mooney Mooney Bridge was designed by Bruce Judd of the then Department of Main Roads (DMR) and built by Enpro Constructions by the free cantilever method of post tensioned concrete. It consists of twin bridges, each bridge with a main span & two approach spans. The span at the western end of the bridge is long, the main span is long and the eastern span is long.〔(【引用サイトリンク】 work=Structurae (): Mooney Mooney Bridge (1986) )〕 The design has been said to demonstrate how good engineering design and good aesthetics are synonymous, and has been used as a standard in the design of bridges throughout New South Wales. They employ a two rail parapet which optimises views of the landscape. The bridges were designed with the natural surroundings in mind and form a simple uncluttered shape so not to detract from the natural bushland of the national park. The three span haunched girders on the bridge were critical to this as were the multiple piers that provide character and strength.〔(【引用サイトリンク】 work=Roads and Traffic Authority: Bridge Aesthetics – Design guidelines to improve the appearance of bridges in NSW (PDF File) )〕 The bridge is the second crossing of the creek in the area, with the original two lane truss bridge that still services Pacific Highway traffic not far downstream of the modern bridge. 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「Mooney Mooney Bridge」の詳細全文を読む スポンサード リンク
