Ep 61. Mountain Roads
- October 28, 2005
Mountain Roads is an episode of the long-running documentary television series Modern Marvels. This episode explores the engineering marvels that make it possible to travel over and through mountains. The episode delves into the challenges that arise when building roads and tunnels through mountainous terrain, and how engineers overcame them.
The episode begins by examining the history of mountain roads, which were initially built for military purposes. The show goes on to explain how these roads were expanded and improved for civilian use, and how they remain an important part of transportation infrastructure today.
Viewers will learn about the unique challenges that arise when building roads in mountainous terrain, including steep grades, rockfalls, and avalanches. The show takes viewers to locations such as the Swiss Alps and the Andes Mountains, where engineers have tackled these challenges head-on with innovative engineering solutions.
The episode also explores the use of tunnels to navigate through mountains. Viewers will learn about the construction of some of the world's longest and most challenging tunnels, including the Gotthard Base Tunnel in Switzerland and the Lærdal Tunnel in Norway. The show delves into the engineering techniques used to create these tunnels, including drilling and blasting, and the use of giant tunnel-boring machines.
Viewers will also discover how technology is changing the way mountain roads are built and maintained. The show takes a look at the use of drones to survey road conditions and detect potential hazards, and how autonomous vehicles could change the way we travel on mountain roads in the future.
Throughout the episode, viewers will be treated to stunning footage of mountain landscapes and the roads and tunnels that traverse them. Expert commentary from engineers and transportation experts provides insight into the unique challenges of building and maintaining roads in mountainous terrain.
Mountain Roads is an episode that will fascinate anyone interested in engineering, transportation, or the natural world. With its blend of stunning visuals and expert analysis, this episode offers a fascinating look at the incredible engineering feats that make it possible to travel over and through mountains.
