In the Isla de la Juventud, the dual carriageway from Nueva Gerona to La Fe is classified as a motorway.
The principal motorways A1 and A4, running from the west to the east of the island and partly unbuilt (most of A1 sections), are the only one numbered and shortened with "A". As well as the Carretera Central covers the entire island, they are projected to perform the same function as motorways.
