}} The Lune Aqueduct is a navigable aqueduct that carries the Lancaster Canal over the River Lune, on the east side of the city of Lancaster in Lancashire, England. It was completed in 1797 at a total cost of £48,320.18s.10d.〔(【引用サイトリンク】 title=A Short History of the Lancaster Canal 1772-1997 )〕 It is a Grade I listed building. ==Construction== The aqueduct was designed by civil engineer John Rennie and constructed by architect Alexander Stevens (died 1796, aged 66).〔〔Fleury, p.30. It should be noted that on page 574 it is stated that his year of death was 1795.〕 The cost of the construction was close to £50,000.〔Fleury, p.116〕 The aqueduct is a traditional structure of that time, consisting of five stone arches supporting the stone trough. Within the piers, special volcanic pozzolana powder was imported to be mixed with cement, which allowed the concrete to set under water.〔(【引用サイトリンク】 title=Lancaster Canal Trust - Lune Aqueduct )〕 Because of the rush to finish the initial stages, before the winter floods, the construction was carried out around the clock and the final bill for the project was over £30,000 over budget (2.6 times the original estimate). This vast overspend was the reason that the Lancaster canal was never joined to the main canal network – there wasn’t enough money for the planned aqueduct over the River Ribble at the southern end of the canal. 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「Lune Aqueduct」の詳細全文を読む スポンサード リンク
