Construction of the Espoonlahti access tunnel will begin in December. Work will begin with the removal of topsoil. Open excavation will begin in December. Blasting for open excavation will be announced by an audible warning signal that is broken before the blast and continuous afterwards. After open excavation, the work will continue underground with building the tunnel in around January 2015. The excavation work for the access tunnel will continue until September 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 Länsiväylä and further afield for use in other construction projects. Haulage will be based on the blasting times. Blasting will occur 1–3 times a day.
