Work will now start to layer the rocks to dissipate the force from waves. This includes excavating the area in front of the east pile line.

A spokeswoman for the project said: ‘The rear pile line has progressed extremely well this week and is now within metres of the Spur Redoubt. There are 202 piles (steel sheets) on the rear line, with about 150 piles left to put in place overall.

‘About 60 metres of drainage has been installed on the eastern side of the works in preparation for the new promenade. We are looking forward to welcoming new marine life to rock revetment tidal pools when they are installed – hopefully we will see seaweed, barnacles, crabs, and, fingers crossed, a starfish or two.’

A second delivery of armour rocks for the defences is anticipated from Monday (weather permitting).
