Tower Bridge London, England My color picture: (Actually of Tacoma Narrows bridge)

A Special Bridge or Subway Committee was formed in 1876 to find a solution to the river crossing problem. It opened the design of the crossing to public competition Horace Jones ended up winning the competition.

Tower Information The tower construction lasted from 1886-1894. Cost was around $3,000,000. The twin hydraulic bascules ("bascule" comes from the French for "see-saw") weigh 1,000 tons each. The two towers each contain over 70,000 tons of concrete.

Function The function of the bridge is to allow car, buses cross the river, while allowing boats to also pass. It is a bascule bridge. The bridge can open and close in 5 minutes.

Tower Information Continued There is a walkway that is 112 feet above water level so that people did not have to wait for the bridge to lower, it was closed in 1910 It was closed due to pickpockets and prostitutes. It was also closed due to lack of use (people preferred to wait for the bridge and watch it). It has now been reopened as part of the museum they put in there.
