DON’T: Mix Up the Tower Bridge and the London BridgeWhatever you might be thinking, they’re not one and the same thing. The London Bridge actually refers to several bridges built over the Thames, the last one of them bought in the 1970s by Lake Havasu City in Arizona and installed there. The current bridge between the City of London and Southwark in Central London is called the Tower Bridge, so, unless you want to look like a fool, don’t just stroll along it singing ‘London bridge is falling down‘.
