Engineers say misidentification happens roughly every ninety seconds during peak season
Staff at Tower Bridge have confirmed they field a correction of mistaken identity roughly every ninety seconds during peak tourist season, as visitors continue to refer to the Victorian bascule bridge, opened in 1894, as “London Bridge,” a plainer structure located roughly half a mile upstream that has, by most accounts, never recovered from the reputational imbalance.
“London Bridge is the boring one,” said one Tower Bridge exhibition guide, who asked not to be named “for London Bridge’s sake.” “It’s a road bridge. This one opens in the middle. People take one look at the towers and the blue paint and assume it must be London Bridge because it’s the famous one, and London Bridge is, technically, also famous, just for being sold to an American in 1968 who may or may not have realised what he was buying.”
The bridge’s bascule mechanism, which raises both halves of the road deck to allow tall river traffic through, is activated roughly 800 times a year, with advance notice published so that pedestrians and drivers are not caught mid-crossing, a system that has functioned without major incident since Victorian engineers first solved the problem of building a bridge close enough to the Tower of London to protect while still allowing shipping access to the Pool of London upstream.
Visitors paying for the glass floor walkway, suspended 42 metres above the Thames within the bridge’s upper walkways, are able to watch river traffic and, on a clear day, pedestrians below looking distinctly nervous about the concept, a sensation staff describe as “the single most reliable reaction we get, regardless of nationality.”
The bridge’s Victorian engine rooms, which once powered the original steam-driven raising mechanism before conversion to electricity in 1976, remain open to visitors as part of the exhibition, alongside original hydraulic machinery staff say continues to draw more genuine fascination than the bridge’s famous silhouette, a phenomenon one engineer called “the eternal triumph of the boiler room over the postcard.”
Painted blue and white to mark Queen Elizabeth II’s Silver Jubilee in 1977, the bridge’s colour scheme has become so associated with its image that staff report visitor disappointment on the not infrequent occasions when scaffolding or maintenance work partially obscures it, a complaint one guide called “understandable, if a little rich given the bridge is one hundred and thirty years old and entitled to the odd touch-up.”

The confusion is not entirely new: the American businessman who purchased the previous London Bridge in 1968 and had it shipped stone by stone to Arizona was, according to widely circulated but unverified legend, under the impression he was buying Tower Bridge, a claim the buyer himself always denied, though Tower Bridge staff say the story “refuses to die, and frankly we’ve stopped correcting that one too.”
