Photos shared by Sinn Féin councillor, John Og O’Kane, illustrated how impassable the road is for most vehicles.
It comes as another Met Office weather warning comes into place later tonight (Saturday) – the second in just 48 hours.
Heavy rain will sweep across Co Armagh from 9pm this evening, with the yellow warning in place until midday on Sunday.
The Met Office said: “Frequent heavy showers will affect southern and central parts of Northern Ireland on Saturday night and on Sunday morning.
“Some 10 mm of rain is possible within an hour, with a few places seeing accumulations of 30 mm in six hours where the most frequent showers occur.”
Needless to say, driving conditions overnight will be horrendous and there will be disruption on many roads prone to flooding.
