There are several connections through the alps being built right now. Gotthard base tunnel through Switzerland, Brenner Base Tunnel through Austria/Italy, and a connection Italy/France. Not all connections through Europe go through the Alps, and u can get a decent average speed even if occasionally dropping below the maximum speed for some rough areas.
I am from the alps, so I am quite aware of this. Still, I can go from Berlin to Munich in the same time it takes me to get through half of Austria as of now. The Brenne Base Tunnel is a needed thing (my grandparents live in the area where traffic is currently going through) but by my judgment it will be too little, too late.
