Mac of Cygnet Posted March 14, 2013 Report Posted March 14, 2013 Barnby Dun Monday 25 March 2013 - Wednesday 27 March 2013 Urgent works are required to enable safe passage through the bridge. This will involve the replacement of defective wigwags which will require the canal to be out of operation during the below times. Wigwags???????
