Constructions Extrêmes: The Paris Metro French Documentary Constructions Extrêmes - Strasbourg: • Constructions Extrêmes: Strasbourg ... Just like the Eiffel Tower, the Paris metro is a true monument. Dating back over a century, it is the beating heart of the city. With its 220 km of track, 302 stations and 14 lines, it is essential to the life of the capital and transports over 5 million passengers per day, 2 billion people each year. Designed by Fulgence Bienvenüe and built in the era of all possibilities, the Paris metro has tested many construction techniques: wooded galleries, tunnel boring machines, shields, ground freezing, steel viaducts and caissons submerged in the Seine... The work, which began at the end of the 19th century, gutted Paris and multiplied its performances. How did the engineers achieve such feats? Today, this heritage masterpiece continues to grow. The Paris Metro goes beyond the limits of the capital, connects with the new 200 km Grand Paris Express network and anchors itself sustainably in the 21st century. ▬▬▬▬▬▬▬▬▬ Subscribe for free to the Free Documentary Français channel: https://bit.ly/4bLSd0x Instagram: / free.documentary Facebook: https://bit.ly/2QfRxbG ▬▬▬▬▬▬▬▬▬ #FreeDocumentary #Documentary #construction ▬▬▬▬▬▬▬▬▬ Free Documentary Français is dedicated to offering you high quality documentaries in French on YouTube for free, with the latest camera equipment used by renowned filmmakers working for famous production studios.
