Ep 2. Tower Bridge

Tower Bridge is the second episode of the seventh season of the popular television series, Modern Marvels. This episode explores the history and engineering behind the iconic Tower Bridge in London, England.

The Tower Bridge was constructed between 1886 and 1894 and is a suspension bridge that spans the River Thames. It was designed by Sir Horace Jones and built by John Wolfe Barry. The bridge measures 800 feet long and 213 feet high, and it features two towers that are connected by walkways for pedestrians.

Throughout the episode, viewers will learn about the unique design of the bridge and the challenges faced by the engineers during the construction process. The bridge is a combination of two types of bridges: a suspension bridge and a bascule bridge.

The bascule bridge operates like a seesaw, with each half of the bridge weighing 1,000 tons. When a ship needs to pass through, hydraulic pumps raise the bridge in just 90 seconds, allowing the ship to pass through. The decks then slowly lower back down to allow cars and pedestrians to cross again.

The episode provides insight into the intricate mechanics that enable the bridge to function properly. Viewers will learn about the massive gears and hydraulics that make it possible for the bridge to raise and lower so quickly and efficiently.

The show also explores the cultural significance of the Tower Bridge. As one of the most recognizable landmarks in London, the bridge is a symbol of the city and its history. The bridge is visited by millions of tourists each year and has appeared in numerous movies and television shows.

The episode features interviews with engineers, historians, and other experts who provide fascinating insights into the bridge's history and construction. The show makes use of stunning visual effects to illustrate how the bridge works and to showcase its impressive size and scale.

Overall, Tower Bridge is an informative and engaging episode that provides a unique glimpse into one of the world's most iconic structures. Modern Marvels has once again delivered an outstanding episode that is sure to captivate viewers and pique their interest in engineering and architecture.
