The old bridge

Fascinating how you can still see what was then the causeway(s) between the two spans of this bridge in Bing Bird's eye view. You can imagine the bridge being there.
I wonder if it was one causeway and the river cut through it, or if there was a small bridge in between. Perhaps the bridge was raised above the causeways on piers. The current crossing has a causeway in between two bridges.
I'll have to get a boat and go investigate.
