Heavy rains and high water levels in the Samaquli dam on Saturday blocked the main road for motorists between Sulaymaniyah and Erbil provinces.
Local authorities in Samaquli directed drivers to take another road, avoiding the risk of accidents on the road.
Authorities called on motorists to pass through the Kuesengj-Erbil road.
On the other hand, the floods in Nineveh, 3 days ago, led to the cutting of Mosul-Erbil road again.
"The road between Erbil and Mosul has been closed again for all types of vehicles for fear of accidents due to the flow of flood water on and off the road," Ninawa governor Nofal al-Aakoub said in a press statement.
