Photos of London's Tower Bridge during construction

Tower Bridge was built between 1886 and 1894. It is a combined bascule and suspension bridge in London, England, over the River Thames. It is close to the Tower of London, from which it takes its name.

It has become an iconic symbol of London.



It consists of two towers tied together at the upper level by means of two horizontal walkways, designed to withstand the horizontal forces exerted by the suspended sections of the bridge on the landward sides of the towers. The vertical component of the forces in the suspended sections and the vertical reactions of the two walkways are carried by the two robust towers. The bascule pivots and operating machinery are housed in the base of each tower.

The following photos of it under construction more than 100 years ago were reportedy only recently rediscovered:
