Shocked to see Gravelly Hill Interchange, Birmingham, UK in the top 19.

The Millau Bridge in southern France is far more impressive but doesn't make the top 19.
Neither does the Route de Napoleon (N85) in France which is described as God's favourite driving road in the World.
Have driven on the Col du Turini but couldn't drive the Stelvio Pass due to the pass being closed due to the snow, which was in June!
