Reunion Island has a network of 5 main roads going all around the island and across the plateaus from Saint-Benoît to Saint-Pierre as well as the road to Cilaos. The country road network is fairly dense in the less mountainous areas. The steep topography and the cyclonic swell are constraints. The "route nationale 2" (the "lava road") is regularly cut by lava flows from the volcano Piton de la Fournaise. In 2009, a new highway, "la route des Tamarins", was inaugurated in the west, linking Saint Paul to Etang Salé.
