The reason this notice has been issued, is that the closure of Shifford Lock has been shortened as only work to repair the handrails will now be carried out. The main work has been postponed until the 2017 to 2018 winter work programme due to weight capacity access issues. The principle contractor has advised the works should not proceed this winter as there is now insufficient time to make good the bridge and carry out the works due to health and safety implications through rushing or without incurring significant risk of over-run.

Please note:
Kings Lock is now open to boating traffic from 4pm on a Friday night until 7am on a Monday morning until the lock reopens on 4 March.  However there is no public access to the lock island or the campsite as this is still a construction site until the end of the works.
