Trans-Papua Highway

The Trans-Papua Highway (Indonesian: Jalan Raya Trans-Papua) refers to 12 road segments, some under construction, across Western New Guinea in Indonesia, located in the island of New Guinea. The roads stretch from Sorong to Merauke with a total length of 4325 km. As of March 2017, 3850 km of roads had been completed and construction on all the roads was predicted to finish in 2018, but construction was delayed in late 2018 due to armed conflict.

The completed road segments include 884 out of Indonesia's 1,068 km border road with Papua New Guinea. As of May 2017, the remaining parts of the road, including 7,000 meters of bridges, were planned to be completed in 2017 and 2018, although not all of the road has been layered by asphalt. As of October 2020, the road was only 200–300 km from completion.

In West Papua and Southwest Papua

Impact
Connections of the road opened access to many isolated areas in Papua region, which has not been possible previously. According to Mongabay, while the road brings benefit to native Papuans in terms of availability of goods and access to healthcare facilities, the road also has potentially harmful consequences such as opening way for illegal logging, intensifying contacts between several tribes that could lead to tribal conflicts, and leaving previously isolated towns and villages economically dominated by those from bigger cities. Analyst of public policies, Agus Pambagio argued that the construction should be advised by anthropologist to take cultural factors into account. The road is also feared to damage Lorentz National Park, which is a protected natural area. Papuan governor Lukas Enembe criticized the road construction, saying that the road "mostly has not been used" by native Papuans. Armed wing of Free Papua Movement rejected the road construction, saying that it is "used for military purposes".

Incident
During the construction of the highway at least 20 construction workers in Nduga were killed by soldiers of the West Papua National Liberation Army (TPNPB), who claimed the highway was meant for military enforcement rather than economic benefit, and was built by military members disguised as civilian workers. As of December 2018, the project is suspended temporarily due to security concerns. In late January 2019, about two months after the attack, project managers said construction would resume using combat engineers from the Indonesian military. About a month later in March, the TPNPB soldiers returned and killed three Indonesian soldiers.
