The last passage on the Cason di Lanza, during the Giro in 2013, seems, although from the other side of the climb, fairly unlikely.
Probably, the road surface was renewed just before the passage. If not, accidents would have been inevitable.
The Cason di Lanza is, not without reason, considered one of the "dangerous roads" in Europe.
Which not only has to do with the road surface, but also with the ascent / descent percentages.
From Pontebba, accessible by bicycle via the Alpe Adria cycle route, which runs from Salzburg to Grado on the Adriatic Sea, take the Via Paularo (you are indeed driving to Paularo on the other side of the mountain) near the Pontebbana. This stream will guide and cross you several times until the summit of the Cason di Lanza.
Initially, the slopes are pretty pleasant. There are houses until beyond Studena Bassa, after which you end up in a forest. After the third crossing of the Pontebbana, after seven kilometers, the percentage suddenly rises to 10%. This is but a small prelude to what awaits you next.
Cattle grids in the road and a sign "Malga Rio Secco" (a malga is a summer residence for shepherds) are usually the harbinger of sturdy climbing. Just like here. Because after you've been able to catch your breath for a moment, an open piece annunces a long strip of far over 10%, with parts up to 14%. But the toughest is yet to come. Again in the forest, in between successive hairpin bends, slopes of 16-17% await you. Climbing now becomes fighting the mountain from turn to turn.
An open strip announces the immense final chord of the heaviest part of the Cason di Lanza. Up to the bend, on a split road, it now rises up to 20%. After a final hairpin bend, the gradient becomes more human again. 9% now seems easy, and when you arrive a bit later on a 4% strip, you even seem to descend. But you are not there yet, because just before the summit the mountain shows its true face again. Again we have to go over 10% to reach the top that is lying ahead of us. Congratulations!
