The structure in front was a railroad bridge that was converted for highway use after the trains stopped running. I would have called it some kind of lattice truss, except they usually have a roof. Maybe the roof was removed when the bridge was converted to vehicular traffic. The bridge is a two-span steel through truss structure supported at midspan on a large stone pier with cutwaters and on seat-type abutments. Note the big rocker bearings supporting the truss.
Since these bridges provide access to the Green Park Railway Station, I wonder if the pier was the former location of the Midland Road Bridge? The strange thing is that we don't see any sign of where a pier might have been attached to the Midland Road Bridge (in yesterday's photo). Also, it's apparent that the Midland Road Bridge doesn't need a support at midspan. However, there is quite a bit of room on the existing pier where another bridge may have stood.
The other Sainsbury's Bridge is a footbridge supported on three precast I girders. We'll take another look at both these bridges tomorrow.
