Approximately 20 years old, the gates will be refurbished to ensure they don't allow leaks, having suffered wear and tear over the past two decades.
The gates each weigh between 2.8 and 3.5 tonnes, with the project costing approximately £180,000. Work is due to be completed by the end of November.
A beautiful waterway
Graham Smith, Canal & River Trust supervisor, said: “We're really pleased to be getting these gates repaired. They've suffered over the years of being constantly opened and closed, so we need to get them out of the water and make some repairs.
"The Stort is a beautiful waterway, and this is a great example of the type of work that needs to be done to keep it in top condition so that everyone can continue to enjoy it.”
