[EN] I think I have found an issue with the route calculated by Kurviger
[DE] Ich glaube ich habe einen Fehler bei der Routenberechnung von Kurviger gefunden
Strada Provinciale Rosazza San Giovanni Oropa (SP513) including the tunnel Galleria Federico Rosazza in the Italian province of Biella is not routable, big detour is suggested. Did not find any hints about a closure. Here is the description of this road by the Province of Biella, department of Planning, Infrastructure, Mobility, Transport and Civil Security: http://www.provincia.biella.it/sites/default/files/2020-02/SP%20513%20Rosazza%20-%20Oropa.pdf.
anybody any idea?
I have been there last week and I can confirm that the road is still closed. Looks like road reconstruction works are on-going. I was there during the weekend so I did not see any workers. My personal estimation is that the closure will still last for quite a while.
With a little imagination and Google you can find the above mentioned website.
According to this, the road should be free again by now - Google maps has been corrected and shows no closing at all. To be on the safe side, maybe use the contact details in the first line of the website?
