The scheme, on the Rover Way foreshore and the banks of the River Rhymney, has been designed to protect properties from the impact of extreme weather events, and from rising sea levels for the next 100 years.

The scheme adheres to Cardiff Council’s adopted shoreline management plan of “hold the line” and has been approved by The Welsh Government via the coastal risk management programme.

Now this process is complete with the contract awarded, work is expected to start on site later this year and will take approximately 3 years to complete.

The total cost of the project is expected to be in the region of £35 million, with the majority of funding provided by Welsh Government.

When built, the scheme will deliver:

  • 150,000 tonnes of rock barrier along the coast to manage erosion and high tides,
  • Sheet piling along the Lamby Way roundabout,
  • Maintained earth embankments,
  • Rock protection for Lamby Way Bridge.
