They have been built for thousands of years as a means of getting between two points.〔(''Dig Diary'' University of Birmingham )〕〔(''Peatlands'' – Northern Ireland Environment Agency )〕 Timber trackways have been identified in archaeological finds in Neolithic England, dating to 500 years before Stonehenge. Radiocarbon methods date them to be about 6,000 years old. ==Chronological development of corduroy trackways== The earlier corduroy trackways are in Germany and Holland. They date to approximately 3000 BC. Their construction is consistently between 3.5 m and 4 m wide, and are simple structures without pegs. The Lindholme Trackway is later and dates to around 2900-2500 BC. The construction for these is mostly 3m, and occasionally up to 4m, wide. Two possible pegs. Later corduroy trackways include the one in Cloonbony, Ireland. This dates to around 2630-2470 BC. The construction of this is 2.5m wide (with the rails at 1.2m apart). This is a more complex structure, pegged at intervals. The Lindholme Trackway fits within a trend of narrowing and increased sophistication during the third millennium BC It has been has argued that this shift could relate to the growing complexity of wheeled transport at the time. 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「Timber trackway」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
