One person has been taken to hospital after a crash involving a number of trucks at Dublin's Port Tunnel.
They articulated lorries collided at the entrance to the southbound bore at around twenty to eight this morning.
It's not known what the condition of the injured man is.
There are still long delays on the M1 - Anne Marie Donnellan from AA Roadwatch has this advice for drivers:
"The Swords Rd from the M50 is fully blocked and delays are back to before J4 on the M1. Motorists should use Coolock Lane as an alternative route.
Traffic wishing to access the Port Tunnel from the Clarehall Rd (R139) are being diverted onto the M50 southbound.
Further along, delays remain through Drumcondra with delays further on from the Clonliffe Rd jct to the NCR jct on Dorset St."
