Hundreds of tonnes of sand from annual harbour dredging is to be used to rebuild Dorset's beaches which were stripped and reshaped by recent high tides and storms.
West Dorset District Council is to carry out work at Lyme Regis and Bridport over the next few weeks. The work will be dependent on the tides and it may be necessary to carry out dredging at night.
Work starts in Lyme Regis Harbour next Wednesday, with Bridport Harbour following in early March.
The work is expected to last a week but is dependent on the weather. The council says harbour users have been informed.
Councillor Robert Gould, Leader of West Dorset District Council, said the work was crucial for maintaining sea defences. He added: "We try to limit the inconvenience by doing it out of season, but we'd like to apologise in advance for any disruption."
