Haiti has two main highways that run from one end of the country to the other. The northern highway, Route Nationale No. 1 (National Highway One), originates in Port-au-Prince, winding through the coastal towns of Montrouis and Gonaïves, before reaching its terminus at the northern port Cap-Haïtien. The southern highway, Route Nationale No. 2, links Port-au-Prince with Les Cayes via Léogâne and Petit-Goâve. The state of Haiti's roads are generally poor, many being potholed and becoming impassable in rough weather.
