Aylesbury Arm Lock Subsidence

Issue date: 3rd April 2013

On 28th March, the towpath side of the lock chamber at lock 12 on the Aylesbury Arm of the Grand Union Canal subsided into the lock. The whole of the lock chamber wall remains in-tact, but has buckled into the lock chamber by about 3 feet, leaving the lock impassable.  Canal & River Trust has closed the canal from locks 11 to lock 13 until further notice. 

The chamber wall will need to be rebuilt, and so a lengthy stoppage is likely. Boats based in Aylesbury Canal Basin are trapped by the stoppage, and so a crane lift out may need to be organised.
