Because of its mountainous landscape and rugged shoreline, Dominica's infrastructure is extremely limited. Its roads, mostly confined to the coast, total 780 kilometers (485 miles), of which 393 kilometers (244 miles) are paved. Most of the island is totally inaccessible by car, and many rural roads are little more than impassable dirt tracks. There are no railways, while the 2 main commercial ports are to be found at Woodridge Bay, near Roseau, and the northwest coast town of Portsmouth. There are also cruise ship facilities at Roseau and at Prince Rupert Bay, near Portsmouth. The island has 2 airports, Melville Hall, in the northeast, and Canefield, north of Roseau. While both have paved runways, neither is able to receive large aircraft. Connections from Europe and North America must be made in Puerto Rico, Antigua, or other larger regional airports.
Telecommunications are also underdeveloped, although cellular phone usage and Internet access are growing, due in part to the development of the offshore financial sector. In 2000, the government announced its intention to liberalize the telecommunications sector by inviting foreign companies to compete in providing services.
