One person has been injured following a crash involving a number of trucks at Dublin's Port Tunnel.
The articulated lorries collided at the entrance to the south bore at around 7.40am this morning.
The injured man has been taken to hospital.
There were long delays on the M1 following the incident, with fuel spill leading to all lanes being closed at the entrance to the south bore of the tunnel.
In a statement this afternoon, gardaí said the fuel spill has now been cleared.
They said: "All driving lanes have now fully reopened to traffic. Emergency services are continuing to use the hard shoulder.
"Motorists are advised to exercise caution on approach and refrain from onlooking."
