Papua New Guinea: Designing the PNG Trans Island Highway

Preparation of Feasibility Study and Detailed Engineering Design of the PNG Trans Island Highway (Aseki to Epo Road)


Papua New Guinea is divided geographically by mountain ranges running east-west through the center of the country. The capital, Port Moresby, is not accessible by road from the north, the Highlands, or the major towns of Lae, Madang, and Wewak.


To enable road access to Port Moresby from the north, the Highlands, and the major towns of Lae, Madang, and Wewak, construction of a north-south road connection is a priority. DT Global is preparing a feasibility study and detailed engineering design for this road.

The planned road is approximately 203 km in length, including a central section referred to as the “missing link” of 123 km. This will traverse through rugged forests and climb over the mountain range, flanked by jagged ridges, rough and precipitous slopes, and occasional plateaus occupied by local food gardens.

Goals and Results

Once constructed, the Trans Island Highway will serve as a significant benefit to the commercial interests and people of Papua New Guinea, who will no longer be forced to use expensive sea or air services to travel across the country.
