Looks similar to the Rhone glacier, but its not, not unless something awful has happened to the road surface recently. Interesting day-for-night effect on the photo!
And Livigno tunnel was correct of course - 4km long and 1 vehicle wide, and about 100m of climb in this direction - great fun on a bike. The sign says something like "at your own risk, mush" to which I reply, "and this differs from other roads how, exactly?"
