What river does the Tower Bridge in London cross?

Tower Bridge in London crosses the River Thames.

The bridge was built between 1886 and 1894 to create a new crossing east of London Bridge. Engineers needed a design that would carry road traffic without blocking ships sailing to the busy Pool of London, so Tower Bridge combines suspension spans with a central bascule section that can lift for vessels.

Architect Horace Jones designed the bridge, while engineer John Wolfe Barry directed its engineering development. It opened on 30 June 1894, with the ceremony led by Edward, Prince of Wales, and Alexandra, Princess of Wales. Its two towers were styled to complement the nearby Tower of London, which also explains the bridge’s name.

A common mix-up is London Bridge. London Bridge is a separate crossing upstream; Tower Bridge is the ornate Victorian landmark with two towers and movable roadway sections. The River Thames is the waterway beneath both bridges, but only Tower Bridge matches the question’s landmark.
