Another roadblock has been set up at Waps, Enga Province, following the earlier blockage near the Wapenamanda township.
Earlier this morning, the Yakuman tribe dug up a section of the Highlands Highway in protest over the removal of a semitrailer that was involved in an accident, where eight young men had died.
Of the eight, six were from the Yakuman tribe, while two were from the Maini tribe of Pausa.
Locals at Pausa have now used a semitrailer to block off the highway, only allowing selected vehicles to pass.
Situation is tense at both ends, whilst there have been reports of pockets of roadblocks along the highway down to Mt Hagen.
Police and PNGDF personnel earlier arrived at the Wapenamanda roadblock to speak with disgruntled members of the Yakuman tribe.
Wapenamanda police station commander, Inspector Robert Bari, told this newsroom that the tribe has agreed to clear the highway and sort out the matter with the owner of the Kenworth semitrailer, while an agreement is yet to be reached with the Maini tribe.
