Which London Underground line crosses the River Thames four times?

The Jubilee line crosses the River Thames four times on its London Underground route.

The crossings occur on the modern eastern section of the line, which runs through south-east London between Westminster and the Greenwich Peninsula before continuing toward Stratford. This repeated movement between north and south of the river is a distinctive feature of the Jubilee line.

The line opened in stages: the original section between Stanmore and Baker Street began operating in 1979, while the major extension to Stratford opened in 1999. That extension created the route’s most recognisable river crossings and connected several major redevelopment areas.

The Jubilee line is often confused with routes that cross the Thames once or twice, including the Victoria and Piccadilly lines. Its silver map colour and modern trains also distinguish it from many older Underground routes.
