Benin, Côte d'Ivoire, Ghana, Nigeria, Togo West Africa 2020
The Abidjan-Lagos corridor connects five of West Africa's largest urban and economic centres and serves ports and inland markets across the region. The project is intended to develop a homogeneous six-lane dual carriageway from Côte d'Ivoire through Ghana, Togo and Benin to Nigeria, using a new alignment while incorporating suitable existing sections where required.
The programme combines hard infrastructure with institutional and trade-facilitation components. Its preparation includes feasibility, environmental and social assessment, detailed engineering design, PPP viability analysis, road-safety audits, spatial-development planning, harmonised transit and border systems and establishment of the Abidjan-Lagos Corridor Management Authority.
ECOWAS is the implementing agency on behalf of the five corridor states. The project treaty and institutional framework provide for ALCoMA to own, develop, manage and operate the supranational highway. This regional governance model is essential because the road must use common standards, concession arrangements and operating rules.
The original PAP II estimate of approximately USD 7 billion was an early baseline. After feasibility and preliminary design, ECOWAS reported a current investment estimate of approximately USD 14.7 billion for a 1,028 km highway, to be financed through a mixed public-private model.
During 2024, national and regional workshops reviewed and validated the detailed-design and trade-facilitation studies. In 2025, ECOWAS reported that the project had entered the final-design phase and that technical experts were considering design options and financing models for fifteen concession lots. In 2026, ECOWAS and AfDB began country missions to initiate financing discussions, and ALCoMA held its first board meeting.
These milestones demonstrate project structuring and investment preparation. Land acquisition, right-of-way protection, investor mobilisation and completion of transaction documentation remain necessary before tendering or physical implementation.
