Our construction contractor, United Infrastructure (UI), is set to begin a new phase of works between Sealand Road and the River Dee, as part of the construction of the Main Onshore Pipeline (the Pipeline).
These works include open-cut trenching, which will require the temporary closure of Deeside Lane as the road must be excavated to install the Pipeline across it. Alongside this, UI's tunnelling subcontractor, Joseph Gallagher Limited (JGL), is set to begin the installation of the Pipeline beneath the River Dee using a direct piping technique.
To allow these works to be carried out safely, Deeside Lane will need to be closed temporarily. Please note that these works do not require the closure of Sealand Road and the River Dee will be unaffected.
Deeside Lane will be closed starting the week commencing 26 October 2026 and is set to reopen in early 2027 (subject to progress).
As Deeside Lane is privately owned, the closure has been agreed with the landowner. A diversion route has been agreed with Flintshire County Council (FCC) and can be found here.
An open-cut trench technique involves digging soil to form a trench, lowering the pipe into the trench, and backfilling it with the excavated soil. The depth of the trench will vary depending on technical factors such as ground conditions and topography. The minimum depth of the trench to the top of the pipe will be 1.2m.
The direct piping works beneath the River Dee require 24-hour operations to ensure the safety of the tunnel and the construction team. These works are due to start in the week commencing 26 October 2026 and are set to complete in early 2027 (subject to progress).

Direct piping is a trenchless construction method that is carried out in a single, continuous process. A remote-controlled boring machine is attached to the front of the Pipeline and is pushed forward from the launch area using a powerful pipe-thrusting system. As the machine excavates the ground, the Pipeline is installed directly behind it. Using this method helps to ensure minimal disruption to key infrastructure and environmentally sensitive areas.
Liverpool Bay CCS Limited (LBCCS), UI and JGL are committed to minimising the impact of these works as much as possible and have considered this within the mitigation measures set out in the Construction Environmental Management Plan (CEMP) approved by FCC.
