The two excavation sub-projects in the West Metro (Länsimetro) construction met last week at the Helsinki-Espoo border.Â
Tunnel excavation began in 2010 in both Espoo and Helsinki. Now 71% – nearly 20km – of the tunnels has been excavated. The first tunnel construction work will begin in late 2012, and the West Metro is scheduled to go into service in late 2015.
