I was sorting through some images earlier and came accross these two of the River Severn; they don't quite merge to form a single panorama, but close enough to give the general impression.
On the left you can see the Severn Bridge, which now carries the M48. On the right you can see the Second Severn Crossing, which carries the re-routed M4.


That is so kewl....hubby has taken panoramic pics too.
