Exploring the History and Material of Old London Bridge
London Bridge, one of the most iconic landmarks in the city, has undergone numerous changes throughout its long history. Starting from the earliest wooden constructions to its current version, the bridge has seen many iterations and materials. This article delves into the materials used during the construction of the oldest wooden London Bridges, providing a glimpse into the engineering techniques of the past.
The Oldest Wooden London Bridges
Long before the construction of the modern London Bridge, which was opened in 1973, a series of wooden bridges spanned the River Thames. These early bridges were crucial for transportation and trade, connecting the bustling metropolis across the river. The oldest known wooden bridge was built around 1014 AD under the command of Saxon King Cnut. This bridge was built and rebuilt multiple times over the centuries, often due to natural disasters and human-made accidents.
Materials Used in Construction
The materials used in the construction of these earliest wooden London Bridges were primarily sourced from the local environment. It is believed that the earliest bridges were lined with soil, a common technique during that period to stabilize the structure and provide better traction for pedestrians and horses.
Wooden Piers
Wooden piers were the primary support structure for the earliest bridges. They were made from sturdy, well-seasoned timbers to ensure longevity. These piers were often buried deep into the riverbed to provide stability against the river’s currents and the weight of traffic. The choice of wood was crucial, often favoring species such as oak, elm, and yew, which were known for their strength and resistance to decay.
Soil Embankment
The use of soil as a lining material served multiple purposes. Firstly, it helped to absorb the impact of the bridge's weight, particularly during times of heavy traffic. Secondly, it provided a stable surface for pedestrians and horses, reducing the risk of accidents. Additionally, soil acted as a natural barrier against erosion, protecting the wooden piers from the force of the river.
Reconstruction and Maintenance
Over the centuries, the wooden London Bridges required frequent maintenance and reconstruction due to the wear and tear from constant use and the effects of the river’s natural forces. Records show that the bridge was rebuilt several times, with improvements being made each time. Techniques for construction and repair evolved over time, incorporating newer materials and methods to enhance the bridge’s strength and durability.
Conclusion
The material choices used in the construction of the oldest wooden London Bridges, especially the use of soil lining, played a significant role in the bridge's functionality and longevity. While these techniques were advanced for their time, they laid the foundation for the current and future versions of the London Bridge.
