The Faroe Islands, a self-governing archipelago within the Kingdom of Denmark located roughly midway between Scotland and Iceland, now boasts a remarkable engineering feat: the world's first and only underwater roundabout. This unique structure is nestled inside the Eysturoy Tunnel, a 6.9-mile undersea passage that opened in December 2020, significantly transforming travel across the islands.
A Revolutionary Transport Link
The Eysturoy Tunnel has dramatically reduced journey times, slashing the trip from the capital, Torshavn, to the village of Runavik from one hour and 14 minutes to a mere 16 minutes. This improvement is part of an extensive tunnel network in the Faroe Islands, which includes 17 land tunnels and four undersea ones, with the deepest section plunging 187 meters (613 feet) below sea level.
Safety and Design Excellence
Driving through an undersea tunnel in the Northern Atlantic might seem daunting, but the tunnels were constructed with this very concern in mind. Teitur Samuelsen, chief executive of Eystur-og Sandoyartunlar, the company operating the tunnels, assured that safety is paramount. "The tunnels are designed by the world's leading engineers and geologists, so safety with regards to the Atlantic above is not an issue," he explained.
Artistic Marvels Beneath the Sea
The underwater roundabout is not just a functional marvel; it is also a visual spectacle. Its striking artwork has been likened to the Northern Lights or even jellyfish, with colours that create a magical driving experience, as reported by CNN. This artistic enhancement is part of a broader initiative to beautify the tunnel network.
More Than Just a Roundabout
Other tunnels in the Faroe Islands also feature artistic installations. For instance, the Sandoy Tunnel, which connects the islands of Streymoy and Sandoy, is adorned with glow-in-the-dark totems that pay tribute to figures from Faroese folklore. Teitur Samuelsen highlighted the rationale behind these investments: "We have a lot of good art in the Faroes, and we'd like to support our artists. In addition, it breaks up the monotony in a long, dark tunnel, so it's good for driving safety."
Geographical and Travel Context
The Faroe Islands comprise 17 inhabited islands along with numerous smaller islets and reefs, often experiencing unpredictable weather that poses challenges for travellers. Súsanna Sørensen, marketing manager of Visit Faroe Islands, humorously noted, "Though we are 18 islands, we often joke that we defy the fact that we are islands (thanks to the tunnels)." Located just a two-hour flight from the UK, this destination offers a unique blend of natural beauty and innovative infrastructure.
In summary, the Eysturoy Tunnel and its underwater roundabout represent a groundbreaking achievement in transport and art, making the Faroe Islands an increasingly accessible and fascinating destination for travellers from the UK and beyond.
