some areas as the surface has become broken up. The Ndjamena-Djibouti Highway is Trans-African Highway 6 connecting the Sahelian region to the Indian Ocean port of Djibouti. The road passes through Darfur in western Sudan and the town of Al-Fashir, scene of the Darfur conflict. Consequently, travel through that area and Sudan–Chad border region is unsafe and development of that road section is at a standstill. The route has a length of 4,219 km (2,622 mi) crossing Chad, central Sudan and northern Ethiopia. Less than half of it is paved and a significant proportion of that is in poor condition. Mountainous terrain in Ethiopia presents challenges to highway engineers. Between Wad Madani in Sudan and Werota in Ethiopia the highway shares the same route as Trans-Africa Highway 4, the Cairo-Cape Town Highway.
6 / Trans-African Highway 6 (TAH 6) or Ndjamena-Djibouti Highway / N'Djamena To Adre / this section of 1.054km within Chad is a highway fairly complete except for the last 150km from Abeche to the Sudanese border town of Adre and a small gap within the city limits of Mongo. It is in need of some maintenance in
