A lock in Old Windsor will be revamped as part of a £2.75million refurbishment project by the Environment Agency (EA).
The River Thames lock will have its gates replaced and repaired and the lock chambers will be reinforced.
It will be closed from November 5 to January 25.
Old Windsor lock will be drained completely in November to allow engineers access to the chamber walls to carry out repairs and reinforcements.
They will also install new timbers to the chamber walls to help protect both the walls and boats during operations of the lock.
Paul Power, EA waterways engineer for the River Thames, said: "Investment in the locks and associated structures is vital to providing those users with a reliable and safe service."
It is part of a programme by the EA to maintain vital structures along the river and is one of 12 to have work carried out.
