Math behind the “Tower Bridge “ 8 years was involved in the construction of this bridge. = 450 laborers/ 5 contractors = 2 enormous pillars (towers) {11,000 tons of steel } Type: movable (bascule) suspension Architecture concept: suspension Length: 880 ft Above the Thames the towers rise 200ft. Materials: steel, masonry Longest single span: 200 ft
Tourist injured, North Tower lift 10 ft. • The London “Tower Bridge” north tower lift, had a horrible accident on May 9, 2009. Which left six people injured. The north tower lift felled at least 30 ft. inside shaft, and caused broken ankles, legs to the six injured travelers, tourist.
Approximately how many cars use this bridge each week or year? What were some special challenges engineers faced? How did they overcome? The tower bridge of London has great strength, it’s weight limit is 17 tones. 40,000 cars tend to cross the bridge every day. Also it opens 900 times for river traffic. This tower Bridge made it easier for pedestrians to cross the bridge. The Thames river, was very shallow, so engineers had to find a way to make this a moveable, horizontal axis (bascule) bridge. In order for the ships to come through, they accomplished this difficult task.
