improvement in transportation. These upgrades have played a key role in supporting Albania's economy, which in the past decade has come to rely heavily on the construction industry. Albania's motorway network has been extensively modernised throughout the 2000s and part of it is still under construction. There are a total of 3 major motorways in Albania: the A1, A2, and A3. When all corridors are completed, Albania will have an estimated 759 kilometers of highway linking it with all its neighbouring countries. The Tirana International Airport Nënë Tereza is the main port of entry for air travellers to the country. The airport is named after the Albanian Roman Catholic nun and missionary Mother Teresa. It has seen a dramatic rise in passenger numbers and aircraft movements since the early 1990s. Today, the Airport handles over 2.2 million passengers per year. In April 2021, Kukës Airport became operational in the north, serving first flights only to Istanbul and Zurich. In 2022, new destinations were announced, including Vienna, Basel/Mulhouse, and Memmingen. Furthermore, Albania plans to build two other airports in the south, which will mainly serve the tourism industry. The busiest and largest seaport is the Port of Durrës. As of 2014, the port ranks as one of the largest passenger ports on the Adriatic and Ionian Sea, with an annual passenger volume of approximately 1.5 million. Other seaports include Vlorë, Sarandë, and Shëngjin. The ports serve an extensive system of ferries connecting numerous islands and coastal cities in addition to ferry lines to several cities in Croatia, Greece, and Italy. The railways in Albania are administered by the national railway company Hekurudha Shqiptare (HSH). The railway system was extensively promoted by the totalitarian regime of Enver Hoxha, during which time the use of private transport was effectively prohibited. Since the collapse of the former regime, there has been a considerable increase in car ownership and bus usage. Whilst some of the country's roads are still in very poor condition, there have been other developments (such as the construction of a motorway between Tirana and Durrës) that have taken much traffic away from the railways. Energy Albania is one of only two countries in the world (along with Paraguay) whose entire electricity production is dependent on hydroelectric power. It is host to five Hydroelectric power stations and a plant including the Fierza, Koman, Skavica and Vau i Dejës which are situated on
