There are 14 road tunnels in Iceland. The first, just 30 metres long, was built in 1948 at Arnarnes near Ísafjörður. The longest continuous single tunnel is Norðfjarðargöng in the eastern fjords, completed in 2017 and 7.9 kilometers long. There's one tunnel currently under construction: Dýrafjarðargöng in the western fjords (pictured). It's due to be opened in 2020 and it will replace the Hrafnseyrarheiði mountain road which is always impassable in winter, thus bringing a year-round circular route around the Vestfirðir one step closer.
