For this a competition was held which was organized under the purview of the Southwark Council in the year 1996, on an international level to select the best design-concept. The Best design was chosen amongst the various entries from all over the world. The bridge was opened up to the public in the month of June in 2000 and the construction process had begun in 1998. The exclusivity of this bridge, apart from its design and engineering marvel was the fact that it was a pedestrian bridge and also meant for cyclists. The cost of construction and the project as a whole was $36,000,000. It is 325 m in length. The structure is made of steel. Before this the last 'river crossing bridge' in the city of London was way back in 2894 and that was the Tower Bridge. In spite of the engineering knowhow and constructional knowledge behind the project, when it was opened to the public, on 10th June 2000, the bridge 'wobbled' from side to side and there was uproar in the media and amongst the general public as well as the government. It was closed after this incident and it was refurbished from different technical perspectives, after which it was again opened up for use in 2002.

The Millennium Bridge was built from the point of view of ushering in a new era into the London cityscape with the bridge's unique design and engineering precision and which would eventually act as a prominent structure for London and UK leading to an increased status all over the world. The Millennium Bridge rests on two huge and heavy piers which are made of concrete. These piers are in the middle of the river which primarily supports this comparatively low hanging suspension bridge. The bridge has got on its both sides; four cables which run simultaneously and these bear partial weight of this huge structure. These are coil cables and they span throughout the whole length of this bridge. These coil cables are 120 mm in diameter. These cables have for support steel boxes which fabricated ones made of steel and are found at an interval of 8m along the length of the cables. The deck of the bridge is manufactured out of aluminum, making it lighter but strong. The cables have been strongly anchored onto the banks for stability. This suspension bridge is comparatively shallow than the normal ones. In fact these cables have a suspension of only 2.3 m which is significantly lower than what is normally found in other bridges of the similar nature. The two main piers are V shaped and they congregate at the bottom to add to strength to the basic structure. These cables are very important as they get their stiffness from the cables. Along the straight axis of the Millennium Bridge the dead load has been calculated to be 2ton/linear m whereas the total dead load in context of cable tension has been calculated to be 22.5MN. The lateral stiffness for this bridge has been kept at same levels of what is found in footbridges all over the
