In the Faroe Islands, challenging weather conditions have led to the development of advanced tunnel infrastructure, including 17 land tunnels and four subsea tunnels, one of which features the world’s only underwater roundabout. These tunnels, built using the drill-and-blast method, have dramatically reduced travel times between islands, cutting the drive from Tórshavn to nearby islands from an hour to just 15 minutes.
Beyond functionality, the tunnels incorporate innovative art. The Eysturoy Tunnel features a sculptural roundabout with shifting colors by artist Tróndur Patursson, while the Sandoy Tunnel, opened in 2023, showcases glowing images inspired by Faroese folklore. Both tunnels also feature immersive soundscapes, enhancing the driving experience.
These engineering feats are transforming life in the Faroes, making remote islands more accessible and sparking economic growth. The Sandoy Tunnel, in particular, has led to increased migration and business development, improving the quality of life for residents and visitors alike.
In the Faroe Islands, wild, unpredictable weather — fierce winds and rain, and thick fog that settles like a curtain — can sometimes make travel by car or ferry problematic. No wonder the Faroese love their tunnels. They’ve built 17 of them on land and four subsea — including the world’s only subsea tunnel with a roundabout that’s underwater.
