The most ambitious project is the construction of line 9 which currently has a length of 8 stations opened in 2009, but once completed it will connect Barcelona airport and the city with a total number of 39 stations.
The network is also connected with seven tram linea and two cable cars, adding 54 km. of length and 115 stations.
There are as well some stations which have not been opened yet, like Gaudi which is placed between the Hospital de Sant Pau and the Sagrada Familia.
All the maps have a license which admits free distribution and modification. However we recommend adding the web to favorites to see the maps updated.
