Description of works

The works included the relocation of services, the urbanization of the surface above the cut and-cover tunnel, the construction of the station and emergency exits, and the installation of the complete track system (track, catenary, telecommunications and signaling).

The rolling stock depots, the Metro de Malaga building and the central traffic control center were also built. The infrastructure was built using the cut and cover method and the track system consists of a ballastless track designed for speeds of 50 km/h on the surface and 70 km/h in the tunnel.

Main Challenges

  • Construction in a high-density area.
  • Relocation of utilities to the oldest part of the city.
  • Changes in tunnel design and construction due to unexpected terrain variations.
  • Constant groundwater level monitoring during construction.
  • Construction underneath the A7 motorway without traffic interruption.

Innovations

Groundwater level monitoring

The open-pit construction could have affected the water table and caused settlements to surrounding buildings. To prevent these problems, the construction of the tunnels included a drainage system with pipes in the walls and under the tunnel that allowed the movement of water through the tunnel infrastructure.

Sustainability

The construction of the Malaga metro has contributed to a 30% reduction in the use of private transport in the city centre, which has improved mobility and the environment. Currently, the metro has more than 40 million users a year.
