Millenium Bridge

One of the biggest tourist attractions to London every year is the Millennium Bridge. This bridge was just completed in the year of 2002 completely after the modifications. The Millennium Bridge which crosses the river Thames and links the bank side to the city.

The bridge is an engineering marvel and has become a great tourist attraction to the city of London. The bridge is owned by bridge house estates which are charitable organizations that are controlled by the city of London. The bridge gives a beautiful view over the river Thames and connects the two backs together making the bridge a very convenient bridge for many pedestrians. The bridge is for pedestrians alone. The bridge is a steel suspension bridge and the design of the bridge was selected through a competition.

The bridge was built with its budget shooting above by about 2.2 million pounds and the bridge releasing late by two months. However even after this the bridge faced problems that had to be corrected immediately and the bridge was closed down again to correct the problems in the bridge. After the problems in the bridge were corrected the bridge was opened again in the year of 2002 and ever since then the bridge has not shown any signs of problems. Being a pedestrian bridge there is no sign of traffic anywhere and you can move along the bridge comfortable as you take a walk and enjoy the beauty of the river Thames. The number of people that were on the bridge was attempted to be restricted when the bridge was opened new due to the arising problems however this did not remove the problems of the Millennium bridge and the bridge was all together closed down to fix the problems.

After 2002 when the bridge was reopened again no attempts to restrict the number of people of on the bridge has been made. The problems with the millennium bridge occurred due to an unusual condition which is known as the synchronous lateral excitation. This condition arose because of many factors. The condition occurred because the builders of the bridge did not account for the movement of the bridge which was coupled with the movement of the pedestrians. When the pedestrians first started using the bridge, they experienced a wobble on the bridge. This was because of the positive feedback of the bridge to the movement of the pedestrians on the bridge.

While building a bridge the load of wind, automobiles etc was considered but the dynamic load of walking pedestrians was over looked by the builders which make the bridge to resonate and the frequency of the people walking. The bridge was then closed down to modify the resonance and after extensive study by the engineers the wobbling effect of the bridge was completely eliminated. The bridge however got its name as the wobbly bridge because of this problem. The Millennium Bridge however is a spending bridge today which attracts tourists form all over London to it.
