Blackfriars Bridge crosses the Thames between Southwark and the City of London, running alongside the Blackfriars railway bridge. It is one of the crossings you use to move between the boroughs.
It was first meant to be called Pitt Bridge after William Pitt the Elder, but the name never stuck. Poor limestone meant constant repairs, and the government finally replaced it.
The old bridge came down in 1864 and Cubitt's replacement did not open until 1869, so the crossing you use in the game is effectively the new bridge a year early. The neighbouring Blackfriars railway bridge carries trains from Southwark into Cannon Street station in the City.
Lambeth Bridge
Lambeth Bridge crosses the Thames between Lambeth and Westminster, near the Palace of Westminster and Lambeth Palace. It is a database landmark.
London Bridge
London Bridge links Southwark and the City of London across the Thames, beside the London Bridge station rail bridge. It is one of the main river crossings in Syndicate.
Tower Bridge
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.
Waterloo Bridge
Waterloo Bridge crosses the Thames between Southwark and the Strand, between Blackfriars and Westminster bridges, and leads straight to Waterloo station.
