Trans–West African Coastal Highway
The Trans–West African Coastal Highway or TAH 7 is a transnational highway project to link 12 West African coastal nations, from Mauritania in the north-west of the region to Nigeria in the east, with feeder roads already existing to two landlocked countries, Mali and Burkina Faso. The eastern end of the highway terminates at Lagos, Nigeria.
