Tickford Bridge  Tickford Bridge, over the River Ouzel (or Lovat) in Newport Pagnell, Buckinghamshire, England, was built in 1810 and is one of the last (21 still remaining) cast iron bridge in Britain that still carries modern road traffic. There is a plaque near the footbridge at the side that gives details of its history and construction. A large set of sluice gates, used to control downstream flooding of the River Great Ouse, is located near the bridge. Tickford Bridge is Grade I listed by Historic England.
