The work consisted of the construction of a 2.5 km long tunnel linking the C-25 road with the C-16 road. The tunnel was excavated using the mechanical-prospective tunneling method (TPM), which consists of excavating an advance tunnel with a tunnel boring machine (TBM) and building a reinforced concrete tunnel behind the TBM.
The work consisted of the construction of a 2.5 km long tunnel linking the C-14 road with the N-240 road. The tunnel was excavated using the mechanical-prospective tunneling method (TPM), which consists of excavating an advance gallery with a tunnel boring machine (TBM) and building a reinforced concrete gallery behind the TBM.
