Residents on the outskirts of Letterkenny say they are terrified a serious accident will take place after a road partially collapsed yesterday.
Motorists traveling through the Glenhaugh area are being asked to drive carefully after the road subsided close to a bridge.
Locals say the hole is so deep it could cause a serious accident if a car ends up in it.
Residents contacted the county council at 9am yesterday but repairs have ye to be carried out.
They say this is the third time in a space of about a year on a one mile stretch of road that this has happened.
