This may not seem like an interesting topic to many of you, but keep in mind Norway´s topography and the necessity to blast lots of dynamite to create tunneler (tunnels) for biler (cars) and tog (trains) to drive through (not to mention syklister-cyclists and folk på fot-people on foot in certain tunneler).  Whether you think this is an interesting topic or not, you have to admit that 900 road tunneler in one country the size of Norway is a lot.  Japan is #2 in number of tunnels in the world.  Tunnelene (The tunnels) in Norway cover about 750 km.  There are both above-ground tunneler and sub-sea tunneler.

See here if you are interested in learning more about Norway´s Tunneling Society and the emphasis they are putting on surface rock excavation, underground construction and related topics.

If you would like to know not only name and length of the  tunnel, you can consult this website for information such as which county the tunnel is in, the year that it was opened, if there is a toll, and which road it is a part of.

And if you are a syklist, you may find this website interesting with the map of all the tunneler and which ones allow syklister or not.

The Halsnøy tunnel is a 4,1 km long sub-sea road tunnel between Sunde at the mainland and Tofte at Halsnøy in Hordaland.

This website provides info about the longest tunnel in the world.: http://www.bergen-guide.com/538.htm

And to utilize the space in mountains, Norwegians park in them too!
