A paved road circles the northern two-thirds of the island, connecting the two main towns, Roseau and Portsmouth, with Melville Hall Airport in the northeast. Much of the road system was severely damaged by the 1979 hurricane; reconstruction averages about 16 km (10 mi) a year. There were about 780 km (485 mi) of roadways in 2002, of which 390 km (242 mi) were paved. There are 2,770 passenger cars and 2,830 commercial motor vehicles on the island. A deepwater harbor has been completed near Roseau on Woodbridge Bay, and both Roseau and Portsmouth also receive ships. Dominica Air Transport and other small airlines connect the main airport with Martinique, Guadeloupe, Antigua, and Barbados. In 2001 there were two airports, both with paved runways, one is a 760-m (2,500-ft) airstrip at Canefield, about 5 km (3 mi) north of Roseau.
