Transport in Benin includes road, rail, water and air transportation. Benin possesses a total of 6,787 km of highway, of which 1,357 km are paved. Of the paved highways in the country, there are 10 expressways. This leaves 5,430 km of unpaved road. The Trans-West African Coastal Highway crosses Benin, connecting it to Nigeria to the east, and Togo, Ghana and Ivory Coast to the west. When construction in Liberia and Sierra Leone is finished, the highway will continue west to seven other Economic Community of West African States (ECOWAS) nations. A paved highway also connects Benin northwards to Niger, and through that country to Burkina Faso and Mali to the north-west.
