Finished in 1894 Tower Bridge is furthest bridge east in central London.The two towers are constructed in a suspension style allowing the central portion (a bascule style) to open to let tall vessels through.
The bridge has two Twitter accounts (really!) one which is an official account about events etc. on the bridge @TowerBridge and a bot account that lets you know when the bridge is opening and closing (helpful should you want a photo of the bridge open!) @twrbrdg_itself.
