Route nationale 5 (RN5) is a primary highway in Madagascar of 402 km.
The route runs from Toamasina to Maroantsetra, a city on the eastern coast of the Madagascar.
The first 160 km until Soanierana Ivongo are paved and in good condition, but the remaining is unpaved and in a bad state of conservation.
