The Port Tunnel will be closed for a number of hours after a truck became stuck inside.
Traffic going southbound will be unable to enter the tunnel for the next few hours.
The truck was above the height restrictions, and emergency services have so far been unable to remove the truck.
The northbound route remains open.
Dublin Port Tunnel - South Bound bore of tunnel is closed until further notice. Please use alternative routes. North Bound remains open @DublinPortCo
