Update from Laois/Gardai:
Tullamore to Kilbeggan N52 open but reduced to one lane in two places where there are snow drifts.
The Laois side of the N80 outside Killeigh is fully blocked and the Portarlington Road outside Tullamore is closed at The Meelaghans. Diggers are either en route to these locations or at the scene.
The Tullamore to Clara Road is passable while the town and bypass roads in Tullamore are quite tricky due to slush.
