Hatton residents could be deprived of vehicular access to the village for as much as six months, it is understood.
People living in Hatton Farm Road, Quarry Road and Park View have been isolated after a culvert was washed out by heavy rain.
On Monday morning last week, teams from Aberdeenshire Council and Scottish Water were on site to assess the situation and keep residents safe after the pavements and road caved in.
Aberdeenshire Roads Manager Alan Burns said: “The culvert has been washed out, which led to the water main bursting, causing scour under the road. The culvert is damaged beyond repair so we have to close the road to traffic and we will look into creating a temporary footpath for pedestrians.”
Mr Burns added: “The weight of the water is pressing down on the gas main so we will take action to save it from bursting.”
As for the time it will take to repair the road, he said: “We don’t know at the moment but once we have done a full assessment we will have a better idea.
“It won’t be a quick fix as we will have to totally replace the culvert. We don’t know the extent of the damage and we won’t know until we remove everything.”
The houses and pub, the Hatton Mill, which lie next to the damaged road have not been affected, with the pub’s car park still in use.
Ritchie Johnson, director of Housing & Social Work, said: “The atrocious weather conditions damaged the road bridge beyond repair, and in order to protect water and gas pipes that serve the village, the decision was taken to close the road. Attention will now turn to building a new bridge, which the council will look to provide as soon as possible.”
