Zona Universitària station
Zona Universitària is a station in the Barcelona Metro and Trambaix networks, in the Les Corts district of Barcelona. It is currently the western terminus of metro line L3 and L9. Also it's served by tram lines T1, T2 and T3. It is named after the Universitat de Barcelona campus of the same name. The metro station is located under "Avinguda Diagonal", between "Carrer González Tablas" and "Avinguda Dr. Marañón". It has five entrances, two on each side of "Avinguda Diagonal", one in "Avinguda Dr. Marañón", and two long side platforms. The entrance lobby features an  artwork by the sculptor Angel Orensanz. The Trambaix stop lies some to the east, in "Carrer d'Adolf Florensa". The metro station opened in 1975, along with the other stations of the section of L3 between Zona Universitària and Sants Estació stations. This section was originally operated separately from L3, and known as L3b, until the two sections were joined in 1982. In February 2016, the south branch of the L9 it opened from Aeroport T1 to this station, as a provisional terminal until it continue to connect the other branch of the line. It is planned that the station will  be served by the common section of metro lines L9 and L10, and work is currently underway to build the L10 and the extension to the upper area of the city of these lines. In the longer term, an extension of line L3 beyond Zona Universitària is planned.
