The Atlantic Road is a 5 mile stretch of motorway flanked by ocean between Molde and Kristiansund, in Norway. It has been voted the “Norwegian Construction of the Century.”
The road is built on several small islands, and is spanned by eight bridges. One can drive with a 360 degree sea view as waves crash under and around.
