London Bridge is a bridge in London, England over the River Thames, between the City of London and Southwark. It is between Cannon Street Railway Bridge and Tower Bridge; it also forms the western end of the Pool of London. London's original bridge made this one of the most famous bridge emplacements in the world. It was the only bridge over the Thames in London until Westminster Bridge was opened in 1750. On the south side of the bridge is Southwark Cathedral and London Bridge station. On the north side is the Monument to the Great Fire of London and Monument tube station.
The current London Bridge was constructed by contractors John Mowlem from 1967 to 1972, and opened by Queen Elizabeth II on 17 March 1973. It is a dull edifice comprising three spans of pre-stressed concrete cantilevers, paid for in part by the sale of the earlier Rennie bridge. It is 928 feet (283 m) long. The cost of £4 million was met entirely by the City of London's Bridge House Estates. The current bridge was built in the same location as Rennie's bridge, which was carefully demolished piece by piece as the new bridge was built, so the bridge would remain in use throughout.
