London Bridge 

London Bridge refers to several historical bridges that have spanned the River Thames between the City of London and Southwark, in central London. The current crossing, which opened to traffic in 1973, 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 This replaced a 19th-century stone-arched bridge, which in turn superseded a 600-year-old medieval structure. This was preceded by a succession of timber bridges, the first built by the Roman founders of London.1

The bridge is the subject of the popular nursery rhyme London Bridge Is Falling Down.
