Pollington Lock to Went Aqueduct towpath closure
From Date: 23/12/2020 15:00
To Date: 29/06/2021 00:00 inclusive
Type: Towpath Closure
Reason: Structure failure
Is the towpath closed? Yes
Closest waterway: Aire & Calder Navigation Main Line
Closest waterway: New Junction Canal
Starts at: Went End Aqueduct
Ends at: Went End Aqueduct
The towpath remains closed as lower water levels upstream of the breach site at Newbridge have resulted in some bank settlement with unevenness underfoot.
Whilst the settlement does not pose a risk to the navigation it does make the towpath unsafe to walk on at this time, and will therefore remain closed until remedial works have taken place.
We will update this notice when we have further information.
We are continuing to carry out inspections of the breach site twice per day to ensure safety of the area. These inspections have confirmed that the repair is structurally sound and there is no further flood risk. We have lowered water levels in the canal to reduce the rate of water loss from the breach and the escaped water is being pumped away into the River Don. The water levels in the canal are being managed through the pumps near Goole dock.
Our project team met on Monday 4 January to begin work to repair the breach. The repair work will first require the removal of the water from a section of the canal around the breach point. This will involve the construction of a temporary dam at two locations by piling across the navigation to create a ‘cofferdam’. The design of these temporary works has commenced.
Once the cofferdam is in place, which we expect to be in the next few weeks, the water in the canal can be pumped around it in order to ensure a constant water supply to feed Goole docks. Until the cofferdam is in place it is difficult to be precise how long a permanent repair will take as this very much depends on what damage we find once the water is removed.
The twice daily inspection of the damaged area of canal bank will continue until this cofferdam is in place to ensure public safety.
