North Nicosia is a major transport hub in Northern Cyprus, where the highways from the other major cities of Northern Cyprus, Famagusta, Kyrenia and Morphou intersect. It is connected to the other cities with modern, four-lane highways: the D-30 highway from Morphou to Famagusta passes through Nicosia, D-25 to Kyrenia. Ercan International Airport has been used for international flights. There is no train or metro system nor plans to develop one. In 2011, plans to build a tram system were put forward but rejected, yet the popular opinion is strongly in favor of establishing one.
