Between Lock 6 Grindley Brook Lock and Bridge 31A Whitchurch Bypass Bridge

Reconstruction works on the canal embankment have now recommenced.

Following further assessment of ground conditions, areas of soft material within the existing embankment are being removed and replaced with compacted granular fill. In addition, the embankment design has been enhanced through the introduction of a Mechanically Stabilised Layer within the lower section of the new embankment, providing additional strength and resilience.

The canal dams recently relocated to the southern end of the embankment will remain in place for the duration of the works.

We will continue to provide updates as the project progresses and thank customers for their continued patience and understanding.

Apologies for the previous update this was added to this notice in error. We apologise for any confusion this may have caused, this update was for Lock 1 Baddiley Lock to Lock 1 Swanley lock on the Llangollen Canal

As part of the ongoing repairs to Culvert 8 at Swanley, we are exploring a potential opportunity to facilitate a one off passage for boats currently affected by the closure. If your boat is currently stranded as a result of the culvert repair works and you would be interested in having a potential passage, please contact our Customer Support Team by Wednesday 30 September. using the following link: Contact us | Canal & River Trust We are currently exploring the options available to facilitate this passage and will provide a further update once we have confirmed whether it can go ahead.

Work has temporarily stopped on the reconstruction of the canal embankment due to unforeseen wet areas of material at the south (New Mills Lift Bridge) end of the works. The wet areas are preventing the imported granular material from being adequately compacted. The existing dams at the south end of the works are to be moved further back in an attempt to reduce water ingress, believed to possibly be infiltrating from the adjacent canal. The re-location of the dams will prevent access to and from the Whitchurch Arm. Additional remedial work is planned to improve the ground using soil stabilisation techniques to allow works to recommence.

We have now completed the reinstatement of the flooded field and repairs to the culvert inlet and outlets. The footpath has been re-opened and the field will be re-seeded with stockproof fencing installed over the next few months. The embankment reconstruction is due to commence this week. The embankment is to be 115-metres long x 5.8-metre high, with 45-degree steep side slopes. It will be constructed using approximately 14,000 tonnes of compacted granular aggregate with geogrid reinforcement at approximately 0.6-metre vertical spacing over its width. A draft design of the concrete canal channel has been completed and is now being finalised for construction purposes. This will be 9.5-metres wide x 1.6-metres deep. Construction of this channel will commence once the embankment is complete. Water is continuing to be pumped around the breach with additional pumps being provided to provide resilience and extra pumping capacity. We will continue to provide updates as work progresses.

We have completed the reprofiling and reinstatement of the flooded field using material recovered from the site and are now installing land drains and applying topsoil. Once work within the flooded field is complete, expected by the end of this week, we will begin reconstruction of the embankment. Laboratory testing has shown that the material recovered from the site contains too high a clay content to be suitable for reuse. As a result, imported granular material will be used in conjunction with a polymer geogrid to form the new embankment. The design of the concrete channel is still being finalised, and further details will be provided once they become available. Water continues to be pumped around the breach. Additional pumps are being installed to provide greater resilience and increased pumping capacity. We will continue to provide updates as work progresses.

Our contractors has now completed the removal of approximately 4,000 tonnes of sand and has re-graded the previously flooded field. The buried culvert has been successfully cleared and is now flowing. Current works are focused on excavating the remaining embankment back to the original breach profile. Material is being carefully removed using tracked excavators and dumpers, with stockpiles being created on site before removal for off-site reuse. Preparation is underway to commence reconstruction of the embankment. This will involve backfilling in layers, incorporating geogrid reinforcement to improve structural strength. Wherever possible, material recovered from the site will be reused in the rebuild. Due to the constrained nature of the site, with a single access point, operations are being carried out as efficiently as possible using specialist plant. Water continues to be managed by pumping around the breach. An alternative flume solution was investigated; however, this has not been progressed due to limited space on site. A reminder that an FAQ page has been created for boaters and can be accessed here. We will continue to provide updates as work progresses.

Just to remind boaters, the closure includes Grindley Brook Locks 1 to 6. The downstream winding hole is Thomason's Winding Hole, located near Bridge 22 (Thomason's Bridge).

We have now completed the draining of approximately 15-million litres of water from the flooded field. This has allowed us to tidy the field and unblock the culvert. A condition survey will be completed of the culvert, but initial indications are that it is in good condition. The ground investigation is to be completed this week, and off-site testing of the materials is ongoing. Excavation of the embankment has commenced. The embankment will be rebuilt, using a technique called reinforced earth, where granular material is strengthened with layers of horizontal polymer geogrid. The canal channel is to be constructed in concrete. Over pumping is continuing, with approximately 40ML/day being transferred past the breach site to Hurl. Fluming of water through the breach site is being investigated.

Works on site have been focused on completing ground investigations, with access to borehole locations provided by our framework contractor. This phase of the works is expected to continue until the end of April. On 18 March, a fish rescue was successfully carried out using specialist fisheries equipment. Access has now been established into the canal bed to allow plant and machinery to complete borehole investigations in this area, and to enable excavation of the embankment to begin in preparation for reconstruction works. The next stage of the works will involve unblocking the buried culvert so that it can be fully inspected. A reminder that an FAQ page has been created for boaters and can be accessed here. We will continue to provide updates as work progresses.

We are today able to share the initial findings of the investigation into the Llangollen Canal breach that occurred at Whitchurch, Shropshire, last December. The full investigation is still ongoing while the site is being drained and cleared, and a further report will be made available once it has concluded in the coming months. Prepared by Canal & River Trust engineers, supported by technical experts, the initial report poses an emerging hypothesis for the possible causes of the breach. At this stage the findings suggest the breach was likely caused by a combination of a number of specific physical characteristics in this location, combined with an undetected long-term, deep-seated leak beneath the canal bed, which we believe caused erosion below the canal bed, ultimately resulting in the collapse of the embankment. While breaches of this scale remain extremely rare, we are already taking forward a number of recommendations from the investigation in order to ensure we take all action possible to enhance the resilience of canal infrastructure. This includes exploring new and innovative technologies to assist in maintenance, inspection and monitoring regimes. We are committed to repairing the canal and restoring navigation as soon as possible in order to get boats back on the water and to allow all users to enjoy this stretch of the canal again. We will post further updates as the repair progresses, and in the meantime thank everyone again for their patience and support. Read the initial findings report here.

A suitably graded access ramp and turning area have now been completed. This will enable safer and more efficient delivery of materials, removing the need for vehicles to reverse onto the A41 trunk road. With this in place, construction of the compound area and safe machine access to the canal can now progress. Over the coming weeks, our team will begin removing trench sheets that were damaged during the breach. At the same time, ground investigations will be carried out to assess conditions and determine which materials can be reused as part of the repair. Major excavation work within the breach cannot begin until these investigations are complete, although machinery will be on site to undertake trial pits and provide access for borehole rigs. Approximately 13 million litres of water have already been pumped from the flooded field into the adjacent foul sewer. A fish rescue is scheduled for this week, after which the remaining water will be fully pumped away. Once this is complete, we will be able to clear and inspect the blocked culvert that passes beneath the canal. Vegetation clearance along both embankments have also been completed. This has included the felling of one mature oak tree and the trimming of a further five oak trees to create the necessary working area for the embankment reconstruction. Over‑pumping continues, with approximately 34 megalitres of canal water pumped past the breach last week. An FAQ page has been created for boaters, which can be accessed here: Llangollen Canal breach boating FAQs | Canal & River Trust We will continue to provide updates as work progresses.

A preferred design has been chosen to repair the breach, using a reinforced soil slope with geogrids and granular materials to rebuild the embankment. Our engineers, together with consultants and specialists, are finalising the design so construction can begin as soon as possible. Our contractors have continued constructing the haul/access road across neighbouring farmland between the breach and the A41, with traffic management installed on the night of 22nd February to allow completion of this access. The flooded field next to the breach is being carefully pumped into an adjacent foul sewer, and a fish rescue will take place once water levels are lowered. Essential vegetation management will start this week to prepare for rebuilding the embankment and canal. Canal water continues to be pumped past the breach to maintain water levels and supply Hurleston Reservoir. We will continue to provide updates as work progresses.

Now that the three boats have been successfully recovered from the breach site, the focus has shifted to repairing the breach as quickly as possible. Significant work has already been progressing behind the scenes, with the Trust working closely alongside our design teams, consultants and specialists to develop the breach repair design. Land access has now been agreed, allowing us to continue installing the site compound and haul road, and to commence dewatering of the flooded field. Essential vegetation clearance and management will also take place in preparation for the main breach repair works. Site access will require traffic management measures on the A41. In the meantime, canal water continues to be pumped past the breach site to maintain canal water levels and to ensure essential water supplies to Hurleston Reservoir are maintained. We will continue to provide updates as work progresses

We are pleased to report that the three boats most impacted by the breach have now been recovered and refloated. Our focus will now turn to the work required to rebuild the canal and reopen it as soon as possible. Given the size and scale of the repair to reinstate the canal, work is unfortunately expected to continue for much of 2026. We appreciate that some boaters on the stretch of canal north of the breach may wish to move their boat before the canal repairs are complete and are grateful that Whitchurch Marina is providing the option for boats to be moved before the breach is repaired. Engineering investigations into the cause of the breach are ongoing, and we will publish a summary of our findings once complete. For further information, please see our FAQs regarding the breach below: Llangollen Canal breach boating FAQs | Canal & River Trust

This week, work at the breach site will focus on recovering the three remaining boats. One boat that was winched clear of the breach before Christmas will be refloated by moving it into a dry section of canal, installing a temporary dam, and reintroducing water. The two boats currently within the breach will also be recovered as part of the planned works. An excavator will first be brought in to carefully reprofile the steep sides of the breach, creating a gradual slope to allow the boats to be winched out for assessment and, where possible, refloating. We will continue to provide updates as work progresses and to support boaters affected by the incident. For any questions or concerns, please contact us on 0303 040 4040 or email

Water levels have continued to recover and good progress is being made on site. A number of boats have successfully re-floated as levels have risen, and assisted passage has been arranged to allow boats to move safely off the pound. Monitoring of water levels is ongoing, and the closure remains in place while detailed repair plans are being developed. We would like to thank boaters, local residents and businesses for their patience and cooperation while this complex incident continues to be managed. Further updates will be issued as progress continues.

The upstream winding hole has been changed from Bridge 31A Whitchurch By-Pass bridge to Bridge 33 Hassells bridge. This is because the winding hole at Bridge 31A is no longer accessible due to the pumping arrangements. For any questions or concerns, please get in touch with us on 0303 040 4040 or email enquiries.westmidlands@canalrivertrust.org.uk. Please note our customer service hours over Christmas.

Since our last update, temporary dams have been installed closer to the breach to reduce the length of canal remaining dry while repair plans are developed. Water has been pumped back into the dammed sections and levels are now recovering. Several boats in the affected area are beginning to refloat, with more expected to be fully afloat later today. One boat that was at immediate risk at the edge of the breach has been safely recovered using specialist equipment and is now secured nearby. Two boats remain within the breach and will be recovered as part of planned works. Engineers have begun detailed investigations into the cause of the embankment failure and will continue this work into the new year. The embankment is subject to a regular inspection regime by the Trust's specialist inspectors and engineers, as is routine for all its assets. Understanding exactly what caused the embankment to be undermined will inform the preparation of a repair plan for the process of rebuilding and reopening the canal. We will continue to support boaters affected by this incident. For any questions or concerns, please get in touch with us on 0303 040 4040 or email .
