Grona Lund have shared some pictures showing the construction of the new invert, and the demolition of some of the buildings. Also a 360 picture as well This shows the construction is very complicated but is coming along well nonetheless. I suspect they won't be able to do much when the park reopens though. In addition, the park has announced a new ride called "Snake" for 2019. Although this will only be a temporary attraction. https://www.gronalund.com/en/rides/snake/ (Not Grona Lund's version, but this will be the same ride basically)
I had totally forgotten about this project. I'm really looking forward to watching be built. Sent from my CLT-L09 using Tapatalk
RCDB has given the invert a name of 'Blue Harvest', though Screamscape believe this to be a codename, with an actual name to be decided on closer to opening. Interestingly, Screamscape made that statement on May 4th this year - Star Wars Day.
@Jonathan on the RCDB link you posted it states "Blue Harvest is a project name. The final name will most likely be different."
It really is incredible that they're building a B&M invert. It's almost like they had a meeting to suggest the most impossible coaster types they could install in their park and chose it as a challenge to prove it can be done. Obviously it's not going to be a record breaking invert but it certainly will be an iconic one for what they've got to work with.
It's pretty incredible what they have done before, almost to the point where you expect nothing less. Gerstlauer - where do you want this bobsled? Gröna - in Jetline
