The Smiths' song "Still Ill" contains the line "under the iron bridge we kissed". Which is the bridge in question?

It appears there may be a bit of debate about which iron bridge Morrissey of the Smiths is referring to in the song "Still lll". There's a photo of him in front of the "Trafford Street Bridge", but then it could be a bridge on the King's Road, Stretford that is near his childhood home, or it could be any one of several other contenders.

However, the "Manchester Evening News" reported a bike tour of locations mentioned in The Smiths' songs and The Iron Bridge on King's Road is one of the sites visited.
