Top road is in Austria, but it's the road to the Tiefenbachferner. The Rettenbachferner climb goes up part of the way (to about 2670 if memory serves me correctly), but the road goes higher - just that that would put most of the last 2km in a tunnel!
The Cime de la Bonette is the next highest, but that is of course a loop that was added on to the existing Col for the purpose of being the highest road.
The highest pure paved pass in Europe is therefore the Col de l'Iseran at 2770m, just ahead of the Stelvio.
Edit: How on earth did Kaunertal get overlooked for the 'great unknown climbs' thread? 38,5km, averaging 5%, and there's a long period of flat in the middle, sure, but then the last 11km or so, you have 5km @ 9,2%, then a bit of false flat before averaging 10,4% for the last bit!
What's more, unlike Nivolet, there's actually a station at the top of the road, so you could most definitely put a race finishing there!
