A man has died following a collision on the M1 overnight.
The crash happened on the southbound side at around 1 o'clock this morning.
The motorcyclist was killed after his bike collided with a truck at Junction 5 Balbriggan South.
That stretch of the motorway has been closed to faciliate a forensic examination.
However a rolling re-opening is currently being managed by Gardai who say it should fully re-open shortly.
Detectives at Balbriggan are investigating the crash and are appealing for any witnesses to contact them.
