To fulfill the environmental requirements for reestablishment of the landscape, the Cut and Cover method was extensively used in a total length of 3.600m. The structures mostly twin, with a width typically of 14,5m (8m-22m), were constructed by cast in situ straight walls, prefabricated arch beams and a final curved cover of reinforced concrete.The system in some places has side openings for the lighting. The area was backfi lled and planted. The excavation was partially retained by pilling or shotcrete and bolting.
