Work on a new £3.9 million scheme to protect Lincoln homes and businesses will start next week.
The Environment Agency (EA) will replace the existing flood prevention walls and sluice gates in the Witham area of Lincoln.
It will take a phased approach to works from June 18. The EA aims to have it all completed by the end of September.
A section of Boultham Avenue will also be closed from June 17 for around six weeks, with diversion routes in place.
All walls will be replaced with bricks as closely matching the originals as possible.
Whilst the EA complete the works, they will use the opportunity to replace the gates at the Great Gowt and Bargate Sluices.
It will also involve installing stop logs to maintain the water levels in the canal.
The scheme is being funded through central government grants from the Department for Environment, Food & Rural Affairs and the Anglian Central Regional Flood and Coastal Committee.
The EA promises that noise will be kept to a minimum, while work is being carried out between 7am to 6pm.
