London's Tower Bridge

London's Tower Bridge is one of the most recognizable bridges in the world. Its Victorian Gothic style stems from a law that forced the designers to create a structure that would be in harmony with the nearby Tower of London.
Plans for the Tower Bridge were devised around 1876 when the east of London became extremely crowded and a bridge across the Thames in that area of the city seemed a necessity. It would take another eight years - and lots of discussions about the design - before construction of the bridge started. 

The bridge, designed by city architect Horace Jones in collaboration with John Wolfe Barry, would eventually be completed in 1894. Five contractors and nearly 450 workers were involved in the construction of the 265 meter long bridge. It took 11,000 tons of steel to build the framework. At the time many people disliked its Victorian Gothic design, but over time the bridge became one of London's most famous symbols.
