It's due to a crash on M1 north bound between Junction 4 Donabate and Junction 5 Balbriggan South which has been cleared.
Gardaí are at the scene and say there are no reports of any serious injuries.
They say all cars are now off the carriageway and they're asking motorists to refrain from onlooking.
