The Eysturoy Tunnel, which opened in December 2020, is notable for housing the world's first underwater roundabout, drawing tourists to the Faroe Islands due to its unique features and striking design that resemble the Northern Lights and jellyfish. This tunnel facilitates improved connectivity within the islands, significantly reducing travel times and encouraging more visitors from the UK, given that it is only a two-hour flight away.

The Faroe Islands, located strategically between Scotland and Iceland, have experienced self-governance since 1948 and are part of the Kingdom of Denmark. Their distinct geographic position leads to unpredictable weather, which has historically hampered transportation. To address these challenges, an extensive network of tunnels has been developed, comprising a total of 21 tunnels, including 17 on land and four underwater, with the Eysturoy Tunnel being the deepest, plunging 187 meters below sea level.

The implementation of such infrastructure not only enhances local travel but is also expected to boost tourism as more travelers become aware of the unique experiences the Faroe Islands offer, particularly the mesmerizing underwater roundabout. This innovative project stands as a significant accomplishment in civil engineering and reflects the region's commitment to improving accessibility and connectivity for both residents and visitors alike.
