Tower Bridge is an iconic symbol of London, known globally for its awe-inspiring architecture and rich history. Constructed between 1886 and 1894, this bridge has been a vital part of London’s transport infrastructure for over a century. As a high-level suspension bridge, Tower Bridge is one of the largest and most famous bridges in the world. However, what is the story behind its construction, and what makes it stand out from other bridges?
History of Tower Bridge
In 1876, the Corporation of London held a design competition to build a new crossing over the Thames. A committee of architects, engineers and other experts had been assembled to review the entries. Sir Horace Jones, the City Architect, was appointed the chief architect for the project. Although the design of the bridge was Jones’s, the engineering part of the project was undertaken by John Wolfe Barry, who was established engineer, and it was Willis, Faber & Co. who provided the wire cable for the bridge.
The design of the bridge was intended to blend in with the surrounding landscape but still be recognized as an engineering marvel. It was decided that a high-level solution would work best due to the increase in shipping traffic and the river’s width. Jones’ single biggest inspiration was the concept of the bascule bridge, which had a counterweight to help lift the road up. The counterweight and the four towers were made of steel whereas the exterior cladding that gives the bridge its unique look is constructed using Cornish granite and Portland stone.
Construction of Tower Bridge
Building Tower Bridge was a mammoth task that required the most skilled workers of the time. The construction took a total of 8 years to complete and involved the efforts of 432 workers, including masons, carpenters, and blacksmiths. Additionally, the use of innovative technology at the time made this British landmark an engineering sensation. The hydraulic system of the bridge was designed by William Armstrong and Company, which was the first time hydraulic power had been used extensively in a project like this.
Due to the complexity of the project, the bridge cost more than was originally planned. The final cost was around £1.2 million and took a staggering eight years to complete. However, Tower Bridge quickly became one of London’s most popular tourist destinations as a result of the engineering and technology involved in its construction.
Conclusion
Overall, the history and construction of London’s Tower Bridge reveal not only the creativity and skill of its designers and builders but also the innovation and dedication necessary to construct a landmark that stands the test of time. This engineering and cultural feat remains a true testament to London’s rich heritage and continues to serve the city to this day, bringing delight and wonder to millions of visitors and locals alike. If you’re ever in London, you must visit the Tower Bridge to experience with your own eyes the awe-inspiring spectacle that lies at the heart of the capital’s skyline.
