Both for the layout and for construction systems, various geotechnical, topographical, urban and environmental constraints have been taken into account. The aim is for stations to be very accessible so that future users optimise travel time.
As part of this work, it is worth mentioning the line tunnel in the area where lines 1 and 2 cross, in addition to the el Perchel Station which will act as the interchange station with the train stations Maria Zambrano (Vialia) and Malaga’s Bus Station. In this case the excavated cavity has had striking dimensions (18 m wide and 13 m high).
The excavation under screens of three excavation levels, in the section under the Beach of Tracks (Suburban, Short-Haul and High Speed Trains) from the Renfe station has also presented a sensitive point due to technical complications in solutions for construction and the significant height of the water table.
Furthermore, the pass under the dual carriageway A-7 through the bored tunnel done without interrupting traffic and the lower Manuel Azaña pass which crosses the Avenida de Andalucía, the main thoroughfare for traffic in Malaga serving 70,000 vehicles each day, have also been significant.
