How Long Did It Take To Build The Tower Bridge?

Answer:

The construction of Tower Bridge in London is an iconic architectural and engineering feat that took a substantial amount of time to complete. The duration from the start to its grand completion was a carefully coordinated endeavor that spanned several years.

Historical Context and Planning

The initial conception of Tower Bridge occurred in response to the dramatic increase in traffic within London during the late 19th century. In 1876, it became evident that a new bridge was necessary to alleviate congestion and provide an additional crossing over the River Thames near the Tower of London, hence the name Tower Bridge. The City of London set up a Special Bridge or Subway Committee tasked with overseeing the bridge’s development, which led to a global competition to find the best design for the new crossing.

Design Selection

The design by Sir Horace Jones, who was the City of London architect, was chosen. His design featured both traditional and innovative aspects with two bridge towers connected at the upper level by two horizontal walkways designed to withstand vertical and torsional effects.

Construction Timeline

  1. Start of Construction (1886):
    The foundation stone of the bridge was laid on June 21, 1886. The initial phase involved constructing the massive piers upon which the bridge would stand. This required extensive work to dredge the riverbed and prepare it to securely house the piers.

  2. Piers and Bascules (1886-1889):
    The construction progressed with the massive piers built into the riverbed. The use of more than 11,000 tons of steel provided the framework for the bridge, and it was clad in Cornish granite and Portland stone to protect the underlying steelwork and blend with the historic environment.

  3. Erection of Towers and Walkways (1889-1892):
    The steel framework for the towers and central span took shape, alongside the installation of the iconic walkways. The bascules — movable sections of the bridge designed to allow ships to pass underneath — were one of the innovative highlights of the construction period.

  4. Completion (1894):
    After eight years of tireless construction work, Tower Bridge was officially opened on June 30, 1894, by the then Prince of Wales (the future King Edward VII) and his wife, Princess Alexandra.

Engineering Challenges

The meticulous construction of Tower Bridge was not without its challenges. Engineers had to account for tides and ship traffic, all while ensuring the stability of the bridge’s innovative movable roadways. Balancing aesthetic requirements with structural integrity posed additional challenges, yet they succeeded in creating what today is considered an exemplary Victorian Gothic Revival style architectural icon.

Key Takeaways

  • Construction Duration: Approximately 8 years (1886 - 1894).
  • Engineering Innovation: The use of bascule technology and the need for both functionality and architectural grandeur.
  • Architectural Style: Victorian Gothic, characterized by its grandeur and detailed decorative elements.

In summary, Tower Bridge’s construction is a tale of impressive engineering achievement and architectural prowess, culminating in a landmark that continues to serve both functional and aesthetic purposes today. The bridge not only facilitated the flow of traffic over the River Thames but also became an enduring symbol of London itself.
