This is not London Bridge

Many people seem to think this is London Bridge. It is not. The old London Bridge did not fall down, but was taken down and moved to Arizona. A story goes around that the person who bought London Bridge also thought he was buying this one.

This is Tower Bridge built (not that long ago) to be similar to the Tower of London which is, in this picture, just to the left at the end of the span. This is a draw bridge. The lower central section rises in two parts to let tall boats pass. The top span is an immovable  walking bridge so that people can 1) get a good view and 2) get to the other side when the bridge is up.

The Thames River looks rough here and it is. There are lots of boats moving up and down.

Short boat trips from the Tower to Westminster (Parliament) are fun and not expensive. They are also included in the Hop On/Hop Off fee.
