Aylesbury Arm Lock Repairs to Finish in November04 November 2013
The repair work being carried out on Buckland Lock on the Aylesbury Arm of the Grand Union Canal, which collapsed in March, is now due to be completed by the end of November. The completion of the work is three months behind schedule and over budget due to lengthy investigations and the complexity of accessing the site. In order to reach the lock Canal & River Trust had to build a road through the adjacent Arla dairy construction site.
CRT believes that the collapse of the lock wall was due to a rare type of clay, which is particularly susceptible to moisture and underlies the lock. The large volume of rain that fell during the year leading up to the collapse caused the clay to swell and push the wall over. Engineers working on the project do not think that the work Arla is carrying out contributed to the collapse.
