This tunnel is the west bore of the two parallel tunnels which will cross the mountain between Pola de Gordon and Pola de Lena. Contract 4 will be built by Copcisa, Brues and Fernandez Construcciones, Azvi and Constructora Hispanica.The TBM will weigh 1,900 tons approximately, whereof 1,200 tons for the TBM alone and 700 tons for the back-up.
