Construction of the Rantaväylä tunnel reaches its midpoint

The Rantaväylä tunnel has now been under construction for a year and a half, and the project has reached its halfway point. About 90% of the quarrying work in the tunnel has been completed. More than half of the earthworks and concrete structures are finished. All filling of water systems has been achieved. The tunnel will be opened to traffic in May 2017.
