Happy days, the Cheshire ring is open, restricted but still open.

"Further monitoring of Marple Lock 11 has shown no significant further movement of the lock chamber, and it has been deemed safe to operate the lock for boats up to 6’10” wide under assisted passage from the afternoon of Thursday 12th July. Canal and River Trust Staff will be available to assist boats through the lock on Thursday between 09:00 and 10:00, and subsequently between the hours of 15:00 -16:00 in the afternoon on each day. Engineers will continue to monitor the lock to identify if any further movement does occur, although we hope that it does not. It may become necessary to shut the lock again at short notice if further movement does occur, and boaters should take this possibility into account when making plans.
It is hoped that we will be able to continue navigation (albeit restricted and assisted) throughout the majority of the summer boating season, before the lock will be shut for more permanent repairs in the autumn. The design of these works is ongoing, and ground investigations may require additional restrictions from time to time, these will be minimised and will be advertised as appropriate."
