Construction Valkyria experiencing major problems

In Gothenburg the construction of Valkyria is experiencing major problems.
Almost all of the coaster steel is erected now, except the part for the tunnel.

Because of the very difficult soil in this part of the Liseberg themepark the constructioncrews can’t do the work they wanted to do.
The park is currently working on solutions to this problem, but most probably all of this will ensure that the opening of the rollercoaster has to be moved to the end of June or even later.
