A section of Broughty Ferry’s seawall has collapsed, leaving the road exposed.
The incident, believed to have occurred in the early hours of Wednesday morning, has forced the closure of Douglas Terrace west of Home Street.
Part of the road has given way with rubble and debris from the collapsed seawall strewn across the harbour below.
Dundee City Council has put barriers around the affected section of road.
However there are concerns that the incoming tide could cause further damage within hours.
Local resident Professor Stephen Partridge said he is not surprised at the scale of the damage following Storm Ciara, which battered Broughty Ferry at the weekend.
He added: “Watching the storm on Sunday I am not surprised to see some damage like this appear. To see it undermining the road like this is quite a surprise.
“The storm, the breaking waves, were coming right over the road and right into the gardens.”
Repairs have been carried out frequently on the seawall in recent years after small areas of damage have occurred.
