Emergency services are at the scene of a very serious crash near Kilmacthomas this morning.
It happened shortly after 8 o'clock on the N25, near McGrath's Cross.
WLR understands a truck and a car were involved.
Gardaí say the road is closed at the moment and is likely to remain closed for some time.
The diversions are as follows:
For traffic coming from Waterford - take the Stradbally Exit on the N25, turn right under the flyover, emerge at Griffin's Garage where you will rejoin the N25;
For traffic coming from Dungarvan - turn left at McGrath's Cross, you will be on the Old Waterford Road and can rejoin the N25 after Griffin's Garage.
Traffic build-up is heavy and drivers are being urged to avoid that stretch if at all possible this morning.
WLR News will have more on this story as we get it.
