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 This replaced a 19th-century stone-arched bridge, which in turn superseded a 600-year-old medieval structure.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.

"New" (19th-century) London Bridge

New London Bridge in the late 19th century

By the end of the 18th century, it was apparent that the old London Bridge — by then over 600 years old — needed to be replaced. It was narrow and decrepit, and blocked river traffic. In 1799, a competition for designs to replace the old bridge was held. Entrants included Thomas Telford, whose proposal of a single iron arch spanning 600 feet (180 m) was rejected as unfeasible and impractical. John Rennie won the competition with a more conventional design of five stone arches. It was built 100 feet (30 m) west (upstream) of the original site by Jolliffe and Banks of Mersthman, Surrey - under the supervision of Rennie's son. Work began in 1824 and the foundation stone was laid, in the southern coffer dam, on 15 June 1825.

Rennie's bridge was 928 feet (283 m) long and 49 feet (15 m) wide, constructed from Haytor granite. The official opening took place on 1 August 1831; King William IV and Queen Adelaide attended a banquet in a pavilion erected on the bridge.

The old bridge continued in use while the new bridge was being built, and was demolished after the latter opened in 1831. New approach roads had to be built, which cost three times as much as the bridge itself. The total costs, around £2.5 million (£192 million as of 2013), were shared by the British Government and the Corporation of London.

In 1896 the bridge was the busiest point in London, and one of its most congested; 8,000 pedestrians and 900 vehicles crossed every hour. It was widened by 13 feet, using granite corbels; but subsequent surveys showed that the bridge was sinking an inch (about 2.5 cm) every eight years; and by 1924, the east side had sunk some three to four inches (about 9 cm) lower than the west side. The bridge would have to be removed and replaced.

Modern London Bridge

The current London Bridge was designed by architect Lord Holford and engineers Mott, Hay and Anderson. It was constructed by contractors John Mowlem and Co from 1967 to 1972, and opened by Queen Elizabeth II on 17 March 1973. It comprises three spans of prestressed - concrete box girders, a total of 928 feet (283 m) long. The cost of £4 million (£47.9 million as of 2013), was met entirely by the Bridge House Estates charity. The current bridge was built in the same location as Rennie's bridge, with the previous bridge remaining in use while the first two girders were constructed upstream and downstream. Traffic was then transferred onto the two new girders, and the previous bridge demolished to allow the final two central girders to be added.

In 1984, the British warship HMS Jupiter collided with London Bridge, causing significant damage to both ship and bridge. On Remembrance Day 2004, various London bridges were furnished with red lighting as part of a night-time flight along the river by wartime aircraft. London Bridge was the one bridge not subsequently stripped of the illuminations, which are switched on at night. The current London Bridge is often shown in films, news and documentaries showing the throng of commuters journeying to work into London City from London Bridge Station (south to north). On Saturday 11 July 2009, as part of the annual Lord Mayor's charity Appeal and to mark the 800th anniversary of Old London Bridge's completion in the reign of King John, the Lord Mayor and Freemen of the city drove a flock of sheep across the bridge, supposedly by ancient right.
