Newport Pagnell
Tickford Bridge, over the River Ouze, was built in 1810. It is the only iron bridge in Britain that still carries main road traffic. This is the oldest iron bridge in the world that is still in constant use. There is a plaque near the footbridge on 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 near the bridge.
