On Thursday 2 January 2020, the highways team carried out an initial assessment on the condition of Short Ferry Road, which remains closed due to flooding.
A small section of the road is still flooded, and the Environment Agency is continuing to pump water away.
Karen Cassar, assistant director for highways, said: "Although much of the road has now emerged from the flood water, the water levels aren't subsiding quickly and the pumping will continue into next week.
"There are minor bank slips at the side of the road at various points, and there is a risk of further slips and the edge of the road falling away whilst the soil is saturated. It would be dangerous to allow traffic back onto the road whilst the verges are so soft.
"We may not know the full extent of the damage to the road for some time, as the ground dries out in the warmer months. We will continue to monitor the state of the road closely.
"The safety of road users is our number one priority, and we'll continue to keep residents updated about when we can reopen the road."
The council's tests used specialist equipment to assess the lower levels of the road, which may have been weakened by the flooding and be liable to collapse under the weight of traffic.
Results of these tests are expected within the next week.
