Despite its popularity and beauty, Tower Bridge is not without its challenges. One of the biggest challenges facing the bridge is its age. At over 125 years old, the bridge is considered a historical and architectural treasure, but its age also means that it requires regular maintenance and upgrades to ensure its longevity.

Another challenge facing the bridge is its location. As one of the busiest bridges in London, Tower Bridge is used by over 40,000 vehicles every day, and this heavy traffic can put a lot of wear and tear on the structure. The bridge is also located in a highly urban area, which can make it difficult to carry out necessary maintenance and renovations.
