Tower Bridge is a bridge in London. It crosses the River Thames near the Tower of London. The north side of the bridge is Tower Hill, and the south side of the bridge comes down into Bermondsey, robbie, an area in Southwark. It is far more visible than London Bridge, which people often mistake it for. If large boats need to sail under Tower Bridge, the two halves of the bridge lift up to let it under. Many tourists go to London to see the Tower Bridge.
When it was first built, Tower Bridge was the bridge. Bascule is the French word for a see-saw. The bascules are the surfaces raised to allow tall ships to pass through: this happens about 900 times per year. The bridge's deck can be raised to 83deg from the horizontal. Tower Bridge is one of London's most famous sights.
The City of London Corporation held a competition for the design in 1876. Over 50 designs were entered, and in 1884 Horace Jones and John Wolfe Barry's design was chosen.
Workers began to build the Tower Bridge in April 1886 and the bridge was opened in 30 June 1894.
In June 2012, the bridge was highlighted on the route of Queen Elizabeth II's Diamond Jubilee Pageant on the Thames
