Ep 2. World's Biggest Arch Bridge

In season 5 episode 2 of Extreme Engineering, viewers are taken on a journey to witness the construction of the world's largest arch bridge in China. The episode begins with an introduction to the challenges faced by engineers in building such a massive feat of engineering and the various technologies used to make it possible.

The bridge, named the Lupu Bridge, spans over the Suzhou Creek in Shanghai, China and is an engineering masterpiece that took over 3 years to build. The arch spans 550 meters and is 100 meters high, making it the longest and highest arch bridge in the world.

Throughout the episode, viewers are given an in-depth look at the entire construction process, from the initial planning stages to the final touches on the bridge. The show explores the use of cutting-edge technology and engineering techniques to make the construction of the Lupu Bridge possible.

One of the most challenging aspects of building the Lupu Bridge was the construction of the arch. The episode shows how engineers had to use a specially designed cable crane system to lift the arch into place. The arch was built on the land and then gradually lifted by crane onto temporary supports before it was finally placed atop the piers. As the weight of the arch was slowly transferred to the piers, the episode showcases the tension and pressure the engineers face to ensure the bridge stays in place.

Another challenge faced by the engineers in constructing the Lupu Bridge was the use of the huge cable stays. The episode shows how engineers and workers had to balance on the cable stays and carefully sling steel cables over the top of the arch to create a support system that would hold up the bridge. The construction process required an immense amount of precision and attention to detail, as every small step had to be carefully planned and executed to ensure the safety and stability of the bridge.

Throughout the episode, viewers also get an insider's look at the life and work of the engineers and workers involved in constructing the Lupu Bridge. The show highlights the dangerous and grueling work conditions and the risks involved in building such massive structures. The episode also showcases the teamwork involved in bringing such a project to life and the sense of pride and satisfaction that comes with building something truly monumental.

In the end, the Lupu Bridge stands as a testament to human engineering and technological prowess. The episode showcases the power of innovation and collaboration and the incredible things that can be accomplished when scientists, engineers, and workers come together for a common goal. Extreme Engineering season 5 episode 2 is a thrilling and inspiring look at what it takes to build the world's biggest arch bridge, and a must-watch for anyone interested in engineering, architecture, or construction.
