Mont Blanc is a long tunnel and the thought of that fire puts me off a little. I have driven through it but it seems to take forever. Many years ago we used the St Bernard, both the pass and the tunnel. I have also towed a caravan through the Susten and Simplon (I think) but I'm not sure if I was supposed to. Whichever route you take the scenery is breathtaking. Dijon is nice and I also like Beaune, especially the wine
