Tower Bridge is the bascule bridge by the Tower of London, built 1886 to 1894, so it only appears in Syndicate's World War I memories. In 1916 it is the Master Spy's base, which Lydia Frye clears for Winston Churchill.
Churchill sends Lydia to deal with enemy zeppelins and the German spy ring at the bridge. Once she clears it, Churchill uses it as his base.
Churchill explains that a German radio is calling zeppelins over London and that a second device must be found. He asks Lydia to search Tower Bridge for the spies behind it; she agrees, remarking that she would settle for the vote as payment. Clearing the facility leads to the dirigible fight from Churchill's armed boat.
With the bridge in British hands, Lydia meets Churchill there to report where the spy cult behind the network is hiding, which sets up the hunt for their leader. In 1916 the Rooks still work the Tower Bridge area, apparently with Lydia's backing.
