Tower Bridge, London, England

Mind the gap—this one opens. Tower Bridge, London

Some bridges connect two sides. Tower Bridge connects history, engineering and a flair for drama. Standing next to the Tower of London and rising over the River Thames since 1894, this London icon literally knows how to lift spirits—and traffic. With its twin towers, blue-and-white paintwork and bascules that open like a giant's drawbridge, Tower Bridge is less a traffic solution and more a stage performer.

When it was first built, our capital city needed a crossing that wouldn't block river trade. The answer? A bridge that could split in half and rise high enough for sailing ships to pass through. Victorian ingenuity powered the hydraulics with steam engines; today, oil and electricity do the heavy lifting. Visitors can step inside to explore its engine rooms and stroll across the high-level glass walkways for a bird's-eye view of the Thames. From its Gothic-style towers to its lifting bascules, the structure continues to bridge the gap between past and present, proving that sometimes, the best way forward is to raise the road.
