More than 400,000 cubic metres of sand has been pumped on to the Lincolnshire coastline to help protect homes and businesses from flooding.
Over the past three months, a dredger has been used to raise beach levels on a 20km (12.5 mile) stretch between Mablethorpe and Skegness.
The Environment Agency said the Lincshore scheme would protect 30,000 properties and 19,000 static caravans.
The project, which began in June, ends this month.
Beaches covered were Trusthorpe, Boygrift, Trunch Lane, Chapel Six Marshes, Wolla Bank and Moggs Eye.
This year marks the start of a five-year programme which will see £30m spent protecting the coastline.
