There's been a serious road collision on the Belleek to Kesh Road in Fermanagh which was being used as a diversion route following an earlier fatal crash outside Pettigo.
This means that anyone wishing to travel from Pettigo to Laghey must go via Enniskillen.
The Fermanagh road is now closed from Rosscoir in Belleek and Leiter in Kesh, forcing all traffic to travel via Enniskillen.
Gardai in Ballyshannon are urging people to avoid the area if possible.
The Pettigo to Laghey Road has been closed since shortly after midday today when a lorry driver, believed to be from Eastern Europe was killed in a single vehicle collision.
It's understood he works for a company based in County Monaghan.
