Dominica is an island nation in the Windward islands in the Lesser Antilles archipelago in the Caribbean Sea. Most people arrive in Dominica via Douglas–Charles Airport, where most commercial flights to the island land. Dominica also utilizes sea transportation and a roadway network. Dominica has 1,512 kilometres (940 mi) of roadways, 762 kilometres (473 mi) of these roadways are paved.Dominica’s road network runs primarily along the coastline and along river valleys. Major roads are two-lane highways which connect the capital, Roseau, with Portsmouth (Edward Oliver Leblanc Highway) and the Douglas Charles Airport (Dr. Nicholas Liverpool Highway). It takes about 45 minutes to drive from Portsmouth to Roseau. Private minibuses form the major public transportation system. These major roads were recently reconstructed with assistance from the People’s Republic of China and the European Union. Due to Tropical Storm Erika, several road surfaces and bridges were damaged by flooding and landslides, including on the newly completed E.O. LeBlanc (Roseau to Portsmouth) and Dr. Nicholas Liverpool Highways (Pont Cassé to Douglas Charles Airport). The only railway known to have operated on the island is a short-lived 36” gauge forestry railway which ran inland from the port of Portsmouth on the northern Leeward coast, 45 km north of Roseau from 1910 until 1913/14
