Tenby Harbour and North Beach users are being asked to be aware of heavy moving machinery over the Easter holidays.
Sand will removed from the mouth of the Harbour and deposited at the north end of the beach from March 26 to 29 as dredging work is carried out. The work will not affect vessel movements at the Harbour.
Tenby Harbourmaster Chris Salisbury said: “We ask that the public please keep clear of the operating area and that dogs are kept on a lead during this time.”
Cllr Rhys Sinnett said: “The timing of the work has been governed by the tide and the dates represented the last opportunity for the work to be carried out before the boats are placed back in the water.”
