There’s a crash on the N7 outbound at Newland’s Cross, affecting a lane of the off-ramp.
Motorists are advised to take care on approach.
Elsewhere there are patches of dense fog on parts of the M7 between Junction 11 and Junction 13.
Visibility is poor in some areas.
However the strong morning sunshine is expected to burn off remaining patches of fog.
The M50 is slow southbound at J6 Blanchardstown and again in parts between Junction 9 Red Cow and Junction 12 Firhouse.
Northbound traffic is busy from Junction 11 Tallaght to Junction 10 Ballymount.
