The Clifton Suspension Bridge isn't just one of the most beautiful bridges in the country - it's also one of the most innovative. It was designed by the legendary engineer Isambard Kingdom Brunel, though he didn't live to see it completed. One of the many astonishing things about the bridge is that, although it was designed to carry horses, it's still in full operation today carrying thousands of cars everyday. It's rightly one of the marvels of Bristol.
