It happened on the M50 Northbound at Firhouse.
The road is closed and traffic is very congested from Ballinteer through Firhouse.
Emergency services are on the scene and Gardai are also on the scene directing traffic.
Motorists should exit the M50 before the Junction 12 exit northbound to avoid delays.
There are no reports of injuries as yet.
