Old Colwyn Coastal Defence Scheme

Griffiths was appointed by Conwy County Borough Council to carry out work on the Old Colwyn Coastal Defence Project in March 2021, with steady progress being maintained throughout the pandemic.

This work targets the section of Old Colwyn Promenade most at risk of collapse – the eastern section between Rotary Way and Splash Point (by Old Colwyn Arches).

The project includes:

• Installation of rock amour to protect the sea wall and promenade
• Extending the existing culvert at Splash Point (by Old Colwyn Arches) through the new rock amour
• Protecting the Dŵr Cymru Welsh Water outfall beneath the new rock amour
• Provision of a new fishing platform at Splash Point (by Old Colwyn Arches)
• Improved beach access structures
• Improved access over existing rock groynes on the beach

Most of the improvements in this phase are to the sea-side of the existing sea wall, providing the first level of protection.

These are major engineering works which require large plant and machinery, including cranes, tracked excavators and dumpers. We can only deliver these works safely by completely closing off this section of the promenade, and both the road and active travel route from Splash Point (by Old Colwyn Arches) to Rotary Way is closed throughout the work, and we apologise for the inconvenience this will cause.

Diversions for vehicles, pedestrians and cyclists are in place. Please refer to the latest information regarding diversions in our Traffic Management section here

To date, we have completed 370m of rock revetment which involved importing 65,000 tonnes of rock armour to the site. New culverts have been constructed along with outfall protection slabs and a new fishing platform. Work is continuing to extend the revetment up to Splash Point – when finished 720m of rock revetment will have been built. Work on the new access ramp to the fishing platform is ongoing. Work to construct the access steps onto the beach will commence once the weather improves to reduce the tidal impact on the new structures.
