Bulolo and Menyamya districts in Morobe Province have been inaccessible over the weekend.
Continuous rain has swept away a section of the Warabung Bridge at the border of Huon Gulf and Bulolo districts.
The gap was 4 metres apart and 5 metres deep. However, another heavy downpour on Sunday night widened the opening to 8 metres.
Morobe Governor Kasiga Kelly Naru visited the scene on Monday and appealed to the people not to demand unnecessarily from authorities.
He also said these roads are national roads and they should not capitalise on the situation by extorting money from travelers.
Several major business houses in Bulolo, like PNG Forest Products, Morobe Mining Joint Venture (MMJV) and Highlands (Zenang) Chickens, have been severely affected.
Naru and Northern Command police chief Peter Guinness will visit the affected bridge and address the youths there.
