The Länsimetro rail line is being ventilated through selected smoke extraction shafts. Ventilation will continue until further notice in order to remove moisture from the tunnels.
The shafts selected for ventilation are the Tiistilä shaft, the Matinsolmu shaft, the Urheilupuisto station’s western shaft, the Otaranta shaft, the Karhusaari shaft, the Myllykallio shaft, and the Salmisaari shaft.
Low, humming noises may be heard coming from the shafts during the ventilation. These shafts were selected because they are not located close to residential areas, so the ventilation noises should not cause any disruption to local residents.
