Travellers on the M9 in Kildare are facing delays as gardai and council staff work to clear any remaining snow.
Motorists have been asked to drive with extra care.
Work began on the hard shoulders from junction two to junction four and continued onto the remaining lanes.
Elsewhere, AA Roadwatch warned that while road and air temperatures were above freezing in most areas, making ice thaw slowly, many routes were slippery.
It said it would still take some time for solid compacted ice and snow to clear from the worst affected areas in the north east and inland Leinster.
A spokeswoman said secondary routes, local roads and higher ground as well as many footpaths remained very icy and slippery. "Continue to take care on all routes as there is a lot of surface water to contend with, this is extremely slippery over ice," she added.
Mat Eireann said Saturday would be dry, with highest temperatures of 5C to 7C degrees generally, however it will again plummet to minus 3C tonight.
Local authorities in Dublin and around the country are expected to decide whether to lift water restrictions.
