This is The World's Most Remote Infrastructure Project

Overview
The Faroe Islands have used a sustained program of road tunnels, including the Eysturoy Tunnel’s undersea roundabout and the 10.8 km Sandoy Tunnel, to reduce the isolation of a 55,000-person archipelago. The projects shorten weather-dependent journeys and support communities, while renewable energy investments—including hydropower and Minesto’s tidal kites—advance a goal of generating all onshore electricity from renewables by 2030.
Key takeaways
- The Eysturoy Tunnel’s undersea roundabout is about 70 m below the surface and lets drivers choose between routes without surfacing between islands.
- The 10.8 km Sandoy Tunnel replaced ferry-only access for an island of about 1,500 people, illustrating how infrastructure can serve small populations as well as major cities.
- The tunnel network has brought more than 90% of the Faroe Islands’ population within the road system and reduced travel dependence on ferry schedules and weather.
- Faroese tunnel construction relies on drill-and-blast excavation, careful geological surveys, concrete lining, and continuous pumping to manage seawater entering through rock fissures.
- Minesto’s tidal kites convert currents into electricity by moving in figure-eight paths; larger devices generate about 1.2 MW and feed power to shore through an undersea cable.
- A proposed tunnel linking Sandoy to Suðuroy could be at least 22 km long and cost nearly $500 million, while the Shetland Islands are considering the Faroese network as a precedent.

Faroe Islands: A Remote, Sea-Dependent Community
- The Faroe Islands are a self-governing territory of Denmark comprising 18 North Atlantic islands and fewer than 55,000 residents.
- Fishing accounts for about 90% of exports and 20% of GDP, while rough weather and limited infrastructure have long made inter-island travel difficult.
- Before the newer tunnels, residents relied on ferries that could be delayed or cancelled by weather.

The Eysturoy Tunnel and Its Undersea Roundabout
- The Eysturoy Tunnel links Streymoy and Eysturoy; its network spans more than 11 km and cuts the Tórshavn–Róavík journey from over an hour to about 16 minutes.
- Its unusual undersea roundabout sits about 70 m below the surface and divides traffic toward two exits.
- The roundabout’s central sculpture depicts figures in traditional Faroese dance, adding local art to the engineering landmark.

Drill-and-Blast Construction and Deep-Tunnel Drainage
- Norwegian contractor NCC used drill-and-blast construction: bore holes, place explosives, remove rock, then line the tunnel with concrete.
- Geological surveys were essential to keep the excavation from reaching the seabed; blasting the Eysturoy Tunnel took a little over two years, followed by about 18 months of fit-out.
- Seawater seeps through rock cracks into reservoirs and is pumped out; one pumping station lies 190 m below sea level.

Hydropower and Minesto’s Tidal Dragon Kites
- The islands have generated hydropower since the 1920s; in 2023, renewables supplied more than half of their electricity.
- Minesto and Faroese utility SEV are developing utility-scale tidal generation near Vestmanna using tethered underwater kites.
- Tidal flow steers each kite in a figure-eight path, turning an onboard turbine; larger units generate about 1.2 MW, while a smaller demonstration model produces about 100 kW.
- The Faroe Islands aim to make all electricity generated onshore renewable by 2030.

The Sandoy Tunnel: Cost, Scale, and Local Benefits
- Opened in December 2023, the 10.8 km Sandoy Tunnel replaced ferry-only access between Streymoy and Sandoy, an island with roughly 1,500 residents.
- The Eysturoy and Sandoy tunnel projects each cost around €80 million; government-backed financing and tolls fund construction and repayment.
- More than 90% of the Faroe Islands’ population is now connected by road, and a proposed tunnel to Suðuroy could extend 22 km and cost close to $500 million.

How Road Links Changed Family Life—and Inspired Other Islands
- Before the Sandoy Tunnel, one resident described a commute to Tórshavn that could take three hours by bus or car, including ferry waits.
- Pregnant residents often had to stay near the hospital in Tórshavn for weeks before giving birth; the tunnel helped make island life practical for one family.
- The Shetland Islands, which share a remote, fishing-based island geography, are studying the Faroese road-tunnel network as a possible model.
