The Eryri Visual Impact Provision (VIP) project, led by National Grid, is a transformative initiative within Snowdonia National Park. Designed to preserve the natural beauty of the region, the project involves replacing 3km of overhead electricity lines across the Dwyryd Estuary with underground cables. Central to the success of this ambitious tunnelling project are the precast concrete tunnel segments being manufactured by Shay Murtagh Precast.
Shay Murtagh Precast is supplying bespoke precast tunnel segments that will line the 3km tunnel, ensuring structural integrity and longevity. These segments are manufactured to withstand challenging geological conditions, including areas with solid geology and sections with tidal flat deposits and glacial sediments. This attention to detail ensures that the segments meet the rigorous demands of the project’s design life, even in aggressive groundwater conditions.
As the Eryri VIP scheme progresses National Grid continues to advance works on the project, which is scheduled for completion in 2029. Recent updates have highlighted the importance of the tunnel infrastructure in improving the picturesque views across Parc Cenedlaethol Eryri National Park while supporting long-term electricity transmission requirements in the region.
The project is set to begin tunnelling in early 2025, with the tunnel boring machine (TBM) designed to handle varying ground conditions, including deep water channels beneath the estuary. Shay Murtagh’s bespoke tunnel segments will play a critical role throughout construction by supporting the safe and efficient delivery of the tunnel lining system.
Once completed, this groundbreaking initiative will significantly improve the visual landscape of Snowdonia by removing pylons and restoring the area’s natural aesthetics. Recent progress updates on the project have also been featured by Ground Engineering Magazine.
