Bridges and Tunnels of Central Europe
Roads in orange, railroads in green. The main arteries can clearly be seen.
As expected, the most assiduous moles are living in the Alps. Also remarkable: the Autoroute embankments in France and the series of tunnels for the ICE high speed tracks in Germany.
Technical note: For identification of tunnels and bridges, I have used the LLE tag of the road and rail shape files provided by EuroGeographics: values lesser than 0 are below surface, values of 2 and more above surface, elements tagged 1 (on surface) and 0 (unknown) being omitted. That's why there are obviously no railroad tunnels/bridges in Italy and Spain!
