This portion of the road had been blocked off since Monday, 4pm.
This was the result of a poor drainage system, which is quite common in the country.
This incident saw the existing culvert blocked by debris, causing the flood water to pave its own path through the few metres of packed soil between the culvert and ground surface.
Only about 3 inches of soil layer was holding the sealed road up.
NCDC swiftly engaged construction company China Harbour to resolve the threat with a temporary fix.
The road was blocked off while construction took place.
John Flex, one of the locals engaged to provide security, told Loop PNG that the road opened to the public by late yesterday afternoon.
But he says this is a temporary solution.
A more permanent work will be done later on.
