The N6 road is one of the 7 national roads of Senegal. It connects Tambacounda in the centre of Senegal to Ziguinchor in Basse Casamance in the south by a route which avoids traversing the Gambia. It is also known as the Route du Sud.
The road runs in a southerly direction from Tambacounda before swinging westwards to follow the southern bank of the Casamance River via Vélingara and Kolda to Ziguichor, where it connects to the N4 road.
