ALGIERS — Hailed as one of the continent’s most ambitious infrastructure projects, the Trans-Saharan Highway represents Algeria’s commitment to turning the ideal of African integration into lasting economic reality.
Connecting Algiers to Lagos, Nigeria, the Trans-Saharan Highway is one of nine major trans-African highway corridors, spanning nearly 10,000 kilometers across six countries: Algeria, Tunisia, Mali, Niger, Chad and Nigeria.
Algeria, aware of its geostrategic position as a bridge between the Mediterranean and sub-Saharan Africa, took the initiative to develop this infrastructure, which ranks among Africa’s oldest transnational road corridors and one of the most comprehensive. The project now achieves an overall completion rate exceeding 90%, with Algeria’s 2,400-kilometer section fully finished.
The project has steadily evolved through robust multilateral cooperation under the Trans-Saharan Highway Liaison Committee (CLRT), headquartered in Algiers, with backing from pan-African and international organizations (African Union, African Development Bank, Islamic Development Bank).
By facilitating the movement of goods, raw materials and agricultural products, the highway helps reduce logistics costs, stimulate trade, and integrate previously isolated regions. It offers landlocked countries—particularly those in the Sahel—a vital land-based alternative to costly maritime and air routes.
The Trans-Saharan Highway thus serves as a cornerstone of the African Continental Free Trade Area (AfCFTA), providing the essential physical infrastructure that underpins the continent’s political integration aspirations.
This infrastructure serves over 400 million people across 6 million square kilometers, unlocking tremendous potential for intra-African trade.
The Trans-Saharan Highway also exemplifies Algeria’s leadership role in promoting pan-African initiatives. Through substantial investment in constructing and maintaining its section— among the longest—Algeria demonstrates its commitment to connecting the continent’s economies as part of a broader vision: establishing Africa as an integrated, self-reliant and competitive region capable of standing alongside major global economic blocs.
Often called “the highway of African unity,” the Trans-Saharan Highway underscores Africa’s capacity for collaborative transformation, with Algeria at the forefront of this continental endeavor.
Algeria’s ambitious vision continues to unfold through several complementary projects currently underway, including the 840-kilometer Tindouf-Zouerate highway. This critical link will connect the Trans-Saharan Highway to Mauritania, strengthening the entire corridor and establishing a vital new gateway to West Africa.
