A man in his 40s has died after he was struck by a car on the R755 at Larragh in Co. Wicklow.
It happened shortly after two o'clock this morning.
He was pronounced dead at the scene, and the driver of the car - a woman in her 20s - was not injured.
The Roundwood/Rathdrum Road remains closed this morning.
That's to facilitate an examination of the area by Garda Forensic Collision investigators.
