Access tunnel excavation to begin in Soukka

Excavation of the Soukka access tunnel will begin in week 50. Work will begin with the removal of tree trunks and topsoil from the construction site. This will be followed by the open excavation of the area. It is estimated that the actual access tunnel excavation will begin in January 2015. The excavation work for the access tunnel will continue until October 2015.

After the access tunnel project, a metro tunnel and metro station site will be excavated. During both work phases, excavated rock will be taken to the Länsiväylä and further afield for use in other construction projects (see map). Haulage will be based on the blasting times. Blasting will occur 1–3 times a day.


Working hours at the site, as determined by the Espoo Environment Department, are as follows:

Earthwork and excavation work
• Mon-Fri 7-18 (quiet work also between 18-22, Sat. 9-18)
Tunnel excavation (grout hole drilling, drilling, scaling)
