Tower Bridge: 1894
Tower Bridge has stood over the River Thames in London since 1894 and is one of the finest, most recognizable bridges in the World. It is the London bridge you tend to see in movies and on advertising literature for London. Tower Bridge is the only Thames bridge which can be raised.
Its middle section can be raised
to permit large vessels to pass the Tower Bridge. Massive engines raise
the bridge sections, which weigh about 1000 tons each, in just over
a minute. It used to be raised about 50 times a day, but nowadays it
is only raised 4 to 5 times a week

London Bridge: 1176
London Bridge is between the City of London and Southward. It is between Cannon Street Railway Bridge and Tower Bridge. London's original bridge made this one of the most famous bridge in the world.
The first London Bridge is thought to have been built by the Romans sometime in the first century, with several rebuilds over the centuries. Eventually wooden bridges were replaced with a stone bridge, the first one being started in 1176 and finished years later
Throughout its history, London bridge has been a busy thoroughfare, and was once lined with shops. The road over the bridge was only about 4m wide between the shops. It was so narrow it often jammed with people, horses and carts. In 1733 a 'keep left' rule was enforced to keep the traffic moving. This became the rule of the road in Britain.
In 1757 the houses and shops on the bridge were demolished. A new bridge was built in 1831 to replace the old one. This in turn was demolished in 1967 and rebuilt in Lake Havasu City, USA, as a tourist attraction. The present london bridge opened in 1973.
