Questions & Answers

Q: What challenges did the Faroe Islands face before building their tunnels?

The Faroe Islands' rugged landscape and rough waters made travel between islands difficult and sometimes impossible. The only way to travel was by boat, which could be time-consuming and impacted by weather conditions.

Q: How are the undersea tunnels in the Pharaoh Islands benefiting the population?

The undersea tunnels in the Pharaoh Islands are significantly reducing travel times, allowing for easier and faster commutes to the capital, hospitals, and public services. They also facilitate the transportation of exports.

Q: What is the purpose of the Monsen Base Tunnel in the Alps?

The Monsen Base Tunnel aims to improve travel efficiency and connectivity between northern and southern Europe. It will provide a direct and faster route for trains, reducing travel times and carbon emissions.

Q: How are the tunnels in Lind, Austria, being constructed?

The tunnels in Lind are being carved through solid rock using a combination of drill and blast methods and a custom-built formwork carriage. Concrete is pumped into the tunnel space between the formwork and the rock to create a smooth lining.

Summary & Key Takeaways

• The Faroe Islands have become experts in tunneling, with over 50 km of road tunnels connecting the 18 rugged islands. They are currently working on their biggest project yet, the "jellyfish roundabout," which reduces travel time between two islands from over an hour to just 15 minutes.

• The Pharaoh Islands are investing nearly $700 million to expand their tunneling system with two undersea tunnels, improving travel efficiency and connectivity on the islands.

• The Monsen Base Tunnel in the Alps is part of the trans-European transport network, aiming to better connect Scandinavia with the Mediterranean. This 64 km tunnel will be the longest underground rail connection in the world once completed in 2028.
