Tower Bridge was built in 1894 and has the reputation of The Bridge of Wonderland on the Thames and the London Main Entrance. The bridge is 240 meters long and a 65-meter-high granite bridge tower stands on each of the two piers in the river. There are two layers of bridge between the two towers. The upper deck is a suspended walkway, and pedestrians can board the bridge. The lower level is the opening bridge. When driving normally and the ship passes by, it is only 90 seconds. The suspension bridge weighing more than 1000 tons will be broken into an eight shape. After the ship passes, it will be automatically put down. After 1976, the tower bridge was changed to electric, and the most spectacular sight of the Tower Bridge was seen at the time of the rise. But it is said that it is rarely turned on now. Den Tower to see the exhibition ticket for adults of 9 pounds, the tower can visit the bridge structure and the historical exhibition of bridges in the city of London.
