This isn’t the London Bridge that’s always falling down in nursery rhymes. That one was actually taken down, block by block, shipped across the Atlantic to Arizona. It was reassembled in 1971, and now spans the Colorado River in Lake Havasu.

The Tower Bridge was built in 1894 and spans the Thames River, connecting the Borough of Southwark with downtown London. The lower ramp raises to allow large ships to pass through.
