The bridge replaced the old footbridge, which was damaged beyond repair in the 1996 Manchester bombing.
The bridge is shaped in the form of a hyperboloid and links the Marks & Spencer/Selfridges building to the Manchester Arndale.
The new footbridge was proposed by Manchester-based architects Hodder + Partners, whose entry won the design competition in 1997.
The structure has won numerous awards and the new footbridge has symbolised the renaissance of Manchester city centre since the bomb.
