Someone on the Italian forum tried to reconstruct the whole new stage (the final descent was deemed too dangerous by CPA so they have to remove it) according to local newspapers rumors and basically we risk to see first a shorter final climb and then ~30 kms extra of flat(tish) terrain to reach the original finish line and do the loop around Genova needed to enter the highway, do the bridge, come out the highway and return to the finish line.
On a side note someone else said that before the presentation of the route they didn't even do the preliminary recons so basically everything could be changed now that they are doing that. Vegni is really doing his best to put on a masterclass of *** direction to go out with a bang...
