| 説明 | The new lock at Stratford on Avon, the seventh to be built, was constructed between August and November 1971. At the time of it’s construction the plan was to dredge a navigable channel all the way from Luddington to Stratford and hence the chamber was built deep enough to be useable without the step in water level provided by the lock and weir at Weir Brake. The site for the lock was adjacent to Lucy’s Mill weir, in a restricted space between the remains of the original double lock and the river. During the excavation of the chamber the anchors for the river side piling failed and the steel piles started to collapse into the excavation. The steel piles were jacked back into line and nine steel portal frames installed to support the lock walls. These arches were the source of much controversy during October and November 1971. This photograph is one of a series showing the construction of the navigation works for two periods during the ‘restoration’. The first period covers May 1969 to the end of July 1970, during which time the first three locks; George Billington, Harvington (Robert Aickman) and Marlcliff (I.W.A.) were built. The second period was June 1971 to June 1972 which spanned the construction of Barton (Elsie & Hiram Billington), Luddington (Stan Clover) and Stratford (Colin P. Witter) Locks. The Upper Avon from Evesham to a junction with the Southern Stratford Canal, in Stratford on Avon, was restored to through navigation by the Upper Avon Navigation Trust between 1969 and 1974, when it was formally re-opened by the Queen Mother. The navigation had been abandoned in the 19th Century and very little of the former navigation works remained. It was made navigable again by building nine new locks and three new weirs and by dredging a substantial length of the river to provide a navigable depth. |
