New Sea Defences Protect Coastal Infrastructure in Old Colwyn, Wales

Major new sea defences have been completed in Old Colwyn, Conwy county, Wales, designed to protect the village promenade and prevent the potential collapse of the railway line and parts of the A55 road.

The £35 million project, which took three years to finish, involved the installation of 160,000 tonnes of rock armour along a 720-meter stretch.

The new stone defences are intended to absorb the power of the roughest seas, raising the promenade by up to 2 meters in places. Over the years, the promenade had become increasingly undermined due to a drop in the beach level. The project was fully funded by the Welsh Government as part of Conwy County Borough Council's commitment to improve sea defenses along the county coastline.

Why this matters: With the predicted rise in sea levels due to global warming, coastal defence is seen as a key priority in Wales. The hope is that the new defences in Old Colwyn will prove to be as effective and long-lasting as the Victorian originals in protecting coastal communities and infrastructure against the impacts of climate change and extreme weather events.

In addition to the rock barricade, the project involved raising the promenade and road by 1.5 metres and adding a fishing platform and new beach access steps. Conwy council also has plans to improve sea defences in other coastal areas, with schemes for Kinmel Bay, Towyn, Llandudno and Llanfairfechan in the pipeline with allocated funding.

The promenade road initially closed in May 2021 for an 18 month period, before the Council secured extra funding to complete all the work required on this stretch, extending the project to early 2024. "This project is part of the Council's commitment to improve sea defenses along the county coastline," a Conwy County Borough Council spokesperson stated. With the Old Colwyn defences now complete, work is set to begin on further coastal protection measures in the region after the summer.
