. . "Not to be confused with London's iconic Tower Bridge. For other uses, see London Bridge (disambiguation)Several historical bridges named London Bridge have spanned the River Thames between the City of London and Southwark, in central London. The current crossing, which opened to traffic in 1974, is a box girder bridge built from concrete and steel. This replaced a 19th-century stone-arched bridge, which in turn superseded a 600-year-old medieval structure."@en . . "Five lanes of theA3" . . "32.0"^^ . "London Bridge"@en . . . "104.0"^^ .
