There are national, department, and county roads in Haiti's road network. The former airport, at the intersection of Autoroute de Delmas and Boulevard Jean-Jacques Dessalines, serves as the hub of the road network. Route Nationale #1 and Route Nationale #2 begin at this intersection.

From its terminus at Rue 22 in Cap-Hatien, Route Nationale #1 (RN1) heads north, passing through Saint-Marc and Gonaves.
Outside of the capital region, Route Nationale #2 (RN2) is more commonly referred to as "Route du Sud" and "Boulevard Jean-Jacques Dessalines" within Port-au-Prince. It begins in downtown Port-au-Prince and heads south before turning west through the capital's western boroughs, Petit-Goâve, Aquin, and its terminus at Avenue des Quatre Chemins in Les Cayes. However, south of Port Salut, its "extension" extends almost to the sea in the southwest.)
The beginning of Route Nationale #3 (RN3) is not far north of the hub of the road network, where RN1 heads northwest from Bon Repos. After crossing the Plateau Centrale via Mirebalais and Hinche, RN3 moves northeast and rejoins RN1 in Cap-Hatien.
At the Carrefour du Fort Léogâne, not too far south of Léogâne, Route Nationale #4 (RN4) splits off from Route Nationale #2. RN4, also known as the "Route de l'Amitié," winds its way south to its center in Jacmel and climbs and descends the Chaîne de la Selle mountain range.
On the northeastern edge of Gonaves, Route Nationale #5 (RN5) departs from Route Nationale #1 and travels north, then northwest, through Gros Morne before reaching its destination near the airport outside of Port-de-Paix.
Just as it is about to enter Cap-Hatien from the south, Route Nationale #6 (RN6) deviates from RN3. Through Terrier Rouge on its way to Ouanaminthe, RN6 travels southeast toward the Dominican border. The bridge over the Massacre River serves as its terminus.
Starting at the aforementioned Avenue des Quatre Chemins in Les Cayes, Route Nationale #7 (RN7) travels northwest across Haiti's southern arm to the outskirts of Jérémie.
Among the National Roads, Route Nationale #8 (RN8) is by far the shortest. At Carrefour Shada in Croix-des-Missions, it ends RN1. It goes through Croix-des-Bouquets in the east, skirts the southern shore of Étang Saumâtre in the west, and reaches the Malpasse border crossing with the Dominican Republic in the east.
After the coup in 1991, there was no maintenance on RN1 and RN2, so the World Bank loaned US$50 million for road repairs. In January 1999, the project was scrapped. The FER (Fond d'Etretient Routiers) was established in 2003 by the World Bank, which reasoned that the cancellation of those projects would halt the development of Haiti's road infrastructure. This was a strategy for reducing corruption, involving local businesses, and preventing these projects from being halted due to political unrest or protests. During his campaign for a second term, President Rene Preval pledged on his Maillages Routiers to construct new roads that would allow the country to advance and rebuild the majority of these roads, which had rapidly deteriorated. When he was unable to obtain the funds from the World Bank, he pleaded for assistance from international donors. This approach was harshly criticized by numerous politicians and the media, but it was enthusiastically supported by a populace that was fervently hoping to see the development of road infrastructure in their towns. As a result, the European Union pledged to aid in the construction of RN6 and RN3. In the interim, Haiti received a $200 million loan from the World Bank to repair RN1 from Titanyen to Cap-Hatien and rebuild RN2, which runs from the River Froide to Aquin. The 2008 hurricane season was a major setback for development because many bridges in multiple locations either collapsed or sustained significant damage that needed to be fixed right away. During the January 12, 2010 earthquake, a significant setback occurred for the majority of the previously halted work on RN1 and RN2. The IDB contributed US$31 million and Canada contributed US$75 million to the construction of RN7, which began in 2009. The earthquake on January 12 also caused it to suffer significant setbacks.
