Choas on M50 as full closure in place due to five-vehicle pile-up ...

One person was 'seriously injured' in the multiple-vehicle crash on the M50 Northbound this afternoon.

They were travelling as a passenger in one of the four vehicles involved in the crash, that happened at around 3.40pm in Ballinteer on Thursday.

Three others, who were travelling in a second vehicle, were also taken to hospital but their injuries are not understood to be serious.

A garda spokesperson said: "Gardaí responded to a collision on the M50 Northbound in Ballinteer, Dublin 16 this afternoon, Thursday 5th October at approximately 3.40pm.

"Four vehicles were involved in the collision.

"The passenger of one vehicle was taken to hospital with what are understood to be serious injuries. The three occupants of a second vehicle were taken to hospital as a precaution. No other injuries were reported.

"The road has since reopened. Enquiries are ongoing."

The congestion on the M50 northbound following the five-vehicle crash earlier today has now cleared and traffic is running smoothly.

Traffic is also running smoothing on the M50 going southbound.

Drivers in Dublin have been advised that there is still heavy traffic in two spots on the M50 this evening - both northbound and southbound.

According to TII Traffic, there are heavy delays northbound between the M50 Junction 16 Cherrywood and Junction 6 Blanchardstown.

Going southbound on the M50, traffic is also heavy between Junction 3 - M1 Interchange and Junction 9 Red Cow southbound as a broken down crane remains on the hard shoulder approaching Junction 9.

All lanes are back open on the M50 northbound at J13 Dundrum after a five-vehicle crash this afternoon.

However, motorists have been warned that there are still "severe delays" of up to 80 minutes on the motorway from Junction 15 at Carrickmines.
