Permanent traffic lights are to be installed at Golden Nook Canal Bridge, Long Lane, Huxley.
To allow the works to be carried out, Long Lane will be closed at the bridge from Monday 5 June for approximately five weeks.
The Council's Director of Place Operations, Maria Byrne said: "Cheshire West and Chester Council has been working with the Canal and River Trust to improve vehicle safety at the bridge and the improvement works will also repair the damaged bridge parapet."
The diversion route will be via Quarry Lane (Christleton) or Eggbridge (Waverton), the A41, Chester Road, Gatesheath Lane, Newton Lane, Tattenhall Road and Red Lane.
The traffic light installation work will cost in the order of £100K and is jointly funded between Cheshire West and Chester Council and the Canal and River Trust, who own the bridge.
Sally Boddy, regional engineer with the Canal and River Trust, added: "This historic canal bridge is regularly damaged by vehicle strikes due to the amount of two-way traffic travelling over it. We are delighted the new traffic light system will reduce traffic flow to one direction at a time. This should greatly reduce the risk of accidents and improve public safety."
