Two lock gates on the Aylesbury Arm of the Grand Union Canal have been replaced after 25 years as part of a £63,000 upgrade.
The gates, which weigh several tonnes each have been craned out of the canal by workmen from the Canal & River Trust.
The gates at lock ten, between Wilstone and Puttenham, have come to end of their working life.
Once installed the new gates will help prevent water leaks and keep the canal topped up with water.
As well as new gates, the 200 year old brickwork alongside the lock has also been repaired as it has suffered over the years from wear and tear.
Vicky Martin, from the Canal & River Trust said: “The Aylesbury Arm is a popular stretch on the Grand Union Canal and after many years of service to thousands of boaters, the gates at lock 10 have finally come to the end of their working life.
“The new hand-crafted lock gates will help to conserve water and keep the canal running smoothly so everyone can enjoy it.”
This winter the trust will be working on around 164 lock gates across the country, as well as carrying out repairs to aqueducts, reservoirs and tunnels.
