The work to shore up sea defences at Hastings is due to continue until June
Thousands of tonnes of shingle and rock have been shipped off the coast of East Sussex for urgent sea defence works.
The first load of boulders, which will be used to strengthen the sea wall in Hastings, was placed on the shoreline.
Groynes are also being refurbished at the east end of Rock-a-Nore Road and work carried out on the harbour arm.
Hastings Borough Council said the work, which is due to be completed in June, was vital to protect homes and businesses along the seafront.
Councillor Peter Finch said engineers at Canterbury City Council, in Kent, who are experts in coastal protection, had designed the project and would oversee the work.
The Department for Food and Rural Affairs (Defra) has provided funding.
"Our contractors have arranged to bring in the larger rocks by sea, which will avoid clogging the road with lorries," he said.
"It is inevitable there will be some noise but this work is vital to protect the homes and business along the seafront. Our contractors are very experienced at this work and will keep disruption to a minimum.
"During the project parts of the beach will be closed to the public."
