Ep 5. Iceland Tunnels

In Extreme Engineering season 2 episode 5, viewers are taken on a journey to Iceland where they will explore some of the most incredible tunnel systems in the world. The episode begins by showcasing the need for a tunnel system in Iceland due to the treacherous weather conditions that make travel between different parts of the island extremely difficult.

Project manager, Matthias Strobl, is tasked with overseeing the construction of a massive tunnel system that will connect the northern and eastern parts of Iceland. The tunnel will run through the country's largest mountain range and reach a depth of over 500 meters.

Strobl and his team must navigate through difficult terrain, unpredictable weather, and unforeseen obstacles as they work to construct the tunnel system. They begin by drilling two massive vertical shafts that will allow the team to access the depths of the mountain range. The team then uses controlled explosions to blast through the rock and create the tunnel system.

As the construction continues, problems arise that threaten the success of the project. The team discovers a complex system of underground rivers that they must divert to prevent flooding in the tunnel. They also encounter high concentrations of dangerous gases, which require additional safety measures to be installed.

Despite the challenges, Strobl and his team persevere and complete the tunnel system on time and on budget. The success of the project is celebrated by Icelanders who finally have a safe and reliable means of transportation between the north and east parts of the island.

Throughout the episode, viewers are treated to stunning shots of Iceland's natural beauty as well as a behind-the-scenes look at the intricate engineering that goes into creating such an impressive tunnel system. The episode highlights the ingenuity and perseverance required to complete such an ambitious project and serves as a testament to human innovation and achievement.
