During the Spanish civil war, Seville became the arrival point for African troops, whilst Iberia served air transport with flights between Tetuán-Seville-Vitoria, Seville-Salamanca and Seville-Larache-Las Palmas. In September 1945, works began on the Seville transoceanic airport, with the construction of runways 05/23, 02/20 and 09/27. One year later, it was classified as a customs point and runways 05/23 and 02/20 were asphalted. In 1948, a goniometer was installed, the runway lighting was completed, and the runways became known as 04/22, 18/36 and 09/27. In 1956, runway 09/27 was extended and runway 18/36 became a taxiway. In 1957, works were carried out on the terminal building and the control tower. Seville Airport was then included in the Hispanic American Agreement for the installation of a supplies base. The facilities were developed near the threshold of 04, rendering the runway out of service. In 1965, an Instrument Landing System was installed. Between 1971 and 1975, the terminal area was renovated, the apron was extended, a new terminal building was constructed and new access roads were developed. In 1989, with a focus on the Seville Expo '92, the apron was extended, and a new access from the national motorway N-IV was opened; a new terminal building and a new control tower to the south of the runway were also built. On 31 July, the new installations were inaugurated. The new terminal expansion program was begun in 2019 to cope with rapid passenger growth. Urban Transport Line of Seville Airport Airport Express connects the bus station Plaza de Armas, in the centre of the city with the airport. It has intermediate stops at strategic points of the city, including the AVE train station of Santa Justa. The whole trip takes approximately 40 minutes. Buses run from 04.30 till 00.45.
