During the construction of the bypass tunnels in northwest Stockholm, the Swedish Transport Administration has measured a larger leakage than expected.

Therefore, the authority has applied for an amendment to the permit for the discharge of groundwater.

But now the Swedish Transport Administration is denied the permit, as the Land and Environmental Court believes that the tunnels must be sealed more.

The court considers that the Swedish Transport Administration should have stopped construction temporarily to carry this out.

- The court questions the Swedish Transport Administration's actions when the leakage increased significantly at the end of 2017. The Swedish Transport Administration already ruled out lining even though it appears from the permit from 2014 that this may be needed.

Large costs could have been avoided if they had prepared for lining, which is an established technology for tunnel construction in areas with high values, says Anders Lillienau, councilor in Nacka District Court, in a press release.
