Tower Bridge: Tour 
Description
Tower Bridge was opened at the end of the 19th century as a pretty unique structure - part suspension bridge, part bascule bridge - the centre arms of the bridge can be lifted in just 60 seconds to allow taller ships access to the Pool of London. During the busiest periods of the Port of London in its early days the bridge could be opened 50 times a day or more, so to help prevent total gridlock, a route for pedestrians was built that goes up the towers and across the walkways high above the bridge deck - meaning pedestrians could avoid having to wait for the bridge to close again to be able to cross. As the number of openings declined, use of the walkways did to and they eventually stopped being used. However they have now been turned into a visitor attraction, with a chunk of the walkway replaced with a glass floor that allows you to look down on the bridge deck below.
