The Town Centre Link Bridge, which has been successfully pushed over 11 live railway lines at Stratford Station, touched down on the other side of the tracks this week.
The 1,600 tonne footbridge - 128m long and 14m wide - will serve millions of spectators during the London 2012 Olympic and Paralympic Games.
Both before the Games and in legacy it will provide a vital link from the existing town centre to Westfield’s £1.45 billion Stratford City Project.
Olympic Delivery Authority chairman John Armitt said: “The town centre link bridge is crucial to getting millions of spectators from Stratford Town Centre to the other side, into the Olympic Park. It will play a key role during the Games and will play a key role in legacy, allowing residents and commuters to walk freely from one side to the other.”
