The tunnel more than three kilometres long to extend Line 2 of Barcelona’s commuter rail suburban train network to terminal T1 of El Prat Airport is now a reality. In December 2018, tunnel boring under the airfield at a depth of 20 metres was completed. Having drafted the project in 2009, Ineco is now managing the works, which include a new intermodal station currently under construction in terminal T2. The company is also drafting the project for the phase two.
