Further along, it’s slowing from J7 Lucan past J6 Blanchardstown, AA Roadwatch said.
Northbound on the M7, there are delays from J8 Johnstown right through to Newlands Cross.
Elsewhere, there are long delays through Sallins coming from the Clane direction (R407).
Eastbound traffic on the M4 is slowest now passing J6 Celbridge.
