Barcelona’s El Prat airport can now be reached by metro from the city centre. Transports Metropolitans de Barcelona (TMB) has finally opened L9 Sud, a driverless 20-kilometre stretch which connects the city centre with El Prat’s Terminal 1. The project, which was originally set to be completed by 2008, has been awaited with much anticipation, especially by those living on the outskirts of Barcelona or in areas without a metro connection, and is expected to transport more than 30,000 passengers per year. The project itself was initially estimated to cost roughly €3 million, but the Catalan government invested 200 additional million on top of the original budget. Despite these changes, L9 Sud will provide passengers a new, more convenient route to El Prat Airport as opposed to the current Rodalies line. Additionally, it will connect to 15 new stations and three other metro lines.
