If you’ve ever taken a trip to Norway then you know what a fjord is–a long narrow body of water with very steep sides making crossing them quite the challenge. Norway’s coastline is 2,500km, but if you count the fjords it skyrockets to 29,000km. So basically, there’s a lot of them.
If you want to travel in a car from the north to the south of the country it will require several ferry trips to get across the fjords. This adds hours to a journey, and it’s a problem the Norwegian government wants to fix without the population opting to fly everywhere or use longer travel routes.
