The Cherwell, Wey and Medway are its main tributaries. It is tidal as far as Teddington in West London and has a flood barrier at Woolwich in southeast London. Tower Bridge is the only bridge over the Thames which can be raised to allow tall ships to pass underneath it. The river Thames in London used to be the busiest port in the world.
