Delmas (Haitian Creole: Dèlma) is a commune in the Port-au-Prince Arrondissement, in the Ouest department of Haiti. Delmas itself is an urban continuation of the capital city. Delmas is also the location of much of the area's commercial and industrial enterprise.
Delmas is traversed by two major roadways. Autoroute de Delmas runs from Route National No. 1 in the northwest corner of the commune to Pétion-Ville on the southeast corner. Boulevard de Toussaint Louverture runs from Autoroute de Delmas to the Toussaint Louverture International Airport and beyond to the commune of Tabarre. Autoroute de Delmas is flanked on both sides by local roads. These roads are numbered, with odd numbers on the north side and even numbers on the south side. For each road, the number is preceded by "Delmas," such as Delmas 60, Delmas 19, etc. Several of these roads are significant and may have other names. Delmas 30B is more commonly known as Rue Nazon and connects Delmas to Port-au-Prince on the south.
