The work will start on Saturday 8 November using weekend closures of the bridge in both directions and is due to be completed, weather permitting, on Sunday 7 December.
Highways Agency Asset Manager Kevin Bown said:
The Sheppey Crossing is a major artery for the people of north Kent so it is vital that we maintain it to the highest standards so that road users continue to benefit from the improved traffic flows in the area. The work we are doing will help to reduce the likelihood of unplanned closures.
We are closing the crossing over the weekend as this is when traffic flow is at its lowest and this will enable us to complete the work more efficiently with as little disruption to road users as possible.
The carriageway will be closed between the Kingsferry slip roads and the Cowstead roundabout. The work will be carried out as follows:
Between 8am on Saturday 8 November until 6pm on Sunday 9 November.
Between 8am on Saturday 15 November until 6pm on Sunday 16 November.
Between 8am on Saturday 22 November until 6pm on Sunday 23 November.
Between 8am on Saturday 29 November until 6pm on Sunday 30 November.
Between 8am on Saturday 6 December until 6pm on Sunday 7 December.
Traffic will be diverted along the Kingsferry Bridge whilst the work takes place. Road users travelling in the opposite direction to the work will not be affected.
