Hi Second-Just because I know you like facts-the original London Bridge kind of fell down-it was actually taken apart, brick-by-brick and shipped to Arizona (someone bought it) where it was reassembled in Lake Havasu, I believe over the Colorado river. It's pretty cool, there's a little amusement park next to it on the river.
A new London Bridge was built over the Thames after that
I got to cross that last summer when we were in London!
