Did you know that there are more than 200 bridges over the River Thames?
We tend to only think of the big ones in central London, but the mighty Thames has many other spans upstream. In his book, Thames Bridges, David C Ramzan explores all 200 of them, delving into their remarkable histories.
For a bit of fun, David has set a little puzzle below. Can you name all seven of these lesser-known Thames bridges? Five fall within the Greater London area and two are in the Home Counties. Answers below.
