Trans-Sahara Highway

Last updated

The Trans-Sahara Highway or TAH 2, formally the Trans-Saharan Road Corridor (TSR), [1] and also known as the African Unity Road, [2] is a transnational infrastructure project to facilitate trade, transportation, and regional integration among six African countries: Algeria, Chad, Mali, Niger, Nigeria, and Tunisia. [2] It runs roughly 4,500 km (3,106 mi) north to south across the Sahara desert from Algiers, Algeria on the Mediterranean coast of North Africa to Lagos, Nigeria on the Atlantic coast of West Africa; subsequently, it is sometimes known as the Algiers–Lagos Highway or Lagos–Algiers Highway.

The TSR is one of the oldest and most complete transnational highways in Africa, having been proposed in 1962, with construction of sections in the Sahara starting in the 1970s. [1] In addition to paving and widening existing roads, the corridor includes thousands of kilometres of cable as part of the "Trans-Saharan Fibre Optic Backbone", a multinational project to increase high-speed telecommunications across the region. [3] The physical infrastructure is to be complemented by policies relaxing cross-border trade and migration and developing logistical services. [1]

The TSR is one of nine Trans-African Highways (TAH) being developed by United Nations Economic Commission for Africa (UNECA), the African Union (AU), the Islamic Development Bank (IsDB) and the African Development Bank (AfDB) with the support of the Arab Bank for Economic Development in Africa, UNCTAD, and other regional and international organizations.

As of 2022, the majority of the highway has been complete, with the central section between Algeria and Niger still being paved. [2]

The Trans-Sahara Highway [4] has a length of about 4,500 km of which about 98% has been paved. It passes through three countries: Algeria, Niger and Nigeria. However, an additional 3,600 km of linked highways to Tunisia, Mali, Chad and Mauritania are considered by planners to be integral to the Trans-Sahara Highway network. The six member countries represent 27% of the continent's GDP and 25% of its population.

The 1,200 km of the highway in Nigeria are part of that country's national paved road network and include nearly 500 km of four-lane divided sections, but highway maintenance is frequently deficient and parts of the road may be in poor condition.

About half the highway, over 2,300 km, lies in Algeria and is mostly in good condition, with the newest sections south of Tamanrasset. From the Algerian border town of In Guezzam to 'Point Zero' on the Niger border is now sealed, with a sand berm extending to either side to disrupt migrant trafficking. [5] [6]

Niger has 985 km of the highway and in 2023 some 900 km had been asphalted, although parts are in poor condition in the south. Further details are given below.

Another crossing of the Sahara was proposed for the Tripoli–Cape Town Highway (Trans-African Highway 3) but this route requires a great deal more construction, faces problems of instability and lawlessness in southern Libya and northern Chad, and is not likely to stimulate trade to the same extent as TAH 2. It may be decades away from completion.

Two other Trans-African Highways cross the Sahara, but at its edges. In 2005 the Cairo–Dakar Highway (TAH 1) in the west along the Atlantic coast became the first fully sealed highway crossing the Sahara from north to south (barring a few kilometres in No Man's Land between Morocco/Western Sahara and Mauritania). [7] The Cairo–Cape Town Highway (TAH 4) follows the Nile in the east, the previous long unpaved sections in Sudan, Ethiopia and Kenya have since been significantly improved. The highway from Nanyuki in Kenya to Moyale at the Ethiopian border is an excellent tarmac road. The roads in Ethiopia and Sudan are all tarmac of good quality as at October 2020.

Announced in 2018, [8] by 2019 a third trade route opened up between Algeria and Mauritania, but has yet to be classified. Established during the French colonial era as a link between Algiers with Dakar to avoid the then Spanish Sahara on the Atlantic, it was closed in 1963. Currently tarmac ends on the Algerian border just south of Tindouf and resumes some 900-kilometres later at Zouerat, passing via Bir Moghrein. [9]

In summary, although ageing paved sections will always deteriorate and require maintenance, currently less than 100 km of the route east of Assamaka remains a marked sandy track. The Trans-Sahara Highway via the central Sahara may well soon be sealed.

Nigeria’s transport network has expanded in recent years to accommodate a growing population. The transport and storage sector was valued at N2.6trn ($6.9bn) in current basic prices in 2020, down from N3trn ($8bn) in 2019, according to the National Bureau of Statistics (NBS). This was reflected in a lower contribution to GDP, at 1.8% in the fourth quarter of 2020, down from 2.1% during the same period the previous year but higher than the 0.8% recorded in the third quarter of 2020. One of the most significant challenges facing the sector is meeting the needs of both large coastal cities and rural inland communities in order to fully unlock the country’s economic potential. This is especially the case with mining and agriculture, both of which are expected to benefit from two large-scale projects: the Lekki Port in Lagos and the Kano-Maradi rail line in the north of the country.

Trans-Saharan trade is trade between sub-Saharan Africa and North Africa that requires travel across the Sahara. Though this trade began in prehistoric times, the peak of trade extended from the 8th century until the early 17th century CE. The Sahara once had a different climate and environment. In Libya and Algeria, from at least 7000 BCE, pastoralism, large settlements and pottery were present. Cattle were introduced to the Central Sahara (Ahaggar) between 4090 to 3500 BCE. Remarkable rock paintings in arid regions portray flora and fauna that are not present in the modern desert.

According to the 2008 census it had a population of 7,045, up from 4,938 in 1998, with an annual growth rate of 3.7%, the second highest in the Tamanrasset province's 2008 boundaries.

Assamakka is a small desert town in northern Niger at a main border crossing with Algeria. It is the only official crossing point between the two nations.

Assamakka is connected to the town of Arlit, 200 km to the south by a road which remains in largely a sand "Piste". From Arlit, the "Uranium Highway", a tarred road built in the 1970s for mining trucks, travels south to Agadez and Niamey.
