How Engineers Use Catastrophes To Innovate Tunnel Design
Synopsis
A 13.6-kilometer tunnel under construction in Istanbul will be the deepest immersed tunnel in the world, designed to improve safety after past disasters.
Synopsis
Istanbul's Marmaray tunnel, a $3.5 billion project, aims to alleviate the city's severe traffic issues. At 13.6 kilometers long and 58 meters deep, it will connect Europe and Asia beneath the Bosphorus Strait. Engineers incorporate lessons from past disasters, such as the 1999 Mont Blanc tunnel fire that killed 39 people. Innovations include advanced evacuation systems and fireproof materials, designed to enhance safety and ensure effective escape routes during emergencies. The project reflects a commitment to improving tunnel safety in urban environments.
