The finishing touches to the new London Bridge Bus Station have been applied just in time for the Olympic Games.
The bus station has been rotated 45 degrees from its original position to enable a new row of bus stops to align with the railway station platforms.
New bus shelters have been designed by Renzo Piano, architect of The Shard and the adjacent office block known as The Place.
The redevelopment of London Bridge bus station has been funded by Sellar as part of the planning agreement for the building of The Shard and The Place.
"This is an excellent example of what joint working between TfL, Sellar, Network Rail and Southwark Council can deliver," said Leon Daniels, managing director of surface transport at Transport for London.
"Careful planning and delivery has brought all these changes together with minimum disruption and with every aspect designed with passengers in mind.
"I am sure passengers will appreciate these improvements whether they pass through London Bridge as part of their daily commute or whether they are visiting the capital this summer for the London 2012 games."
Irvine Sellar said: "It gives me, and the whole London Bridge Quarter team, great pleasure to see the new bus station unveiled.
"It forms an integral part of the London Bridge Quarter masterplan that is helping create a 21st century transport hub as part of this new business district which includes London's newest landmark, The Shard. We believe this, and our other infrastructure works, will help make London Bridge a more efficient and effective station."
