Work will start later this month on a section of the riverside path just south of Newark Road, Lincoln.
The existing stone footway along the bank of the River Witham behind the Esso Garage will be extended for approximately 90 metres southwards to protect the bank from erosion and make the path safer and more accessible.
Work will start on Monday 12 April, and is expected to last until Friday 7 May 2021. The footpath will be closed whilst work takes place.
Chris Miller, countryside services team leader, said: "The existing path here has become uneven and narrowed, so we're upgrading it to a more robust stone surface to make sure people can enjoy the riverside path safely.
"Thank you to local residents for bearing us whilst we upgrade this path. I hope these improvements help encourage more people to access this stretch of the Witham."
