under the bridge

went up to town again today as we were going on an evening boat trip on the Thames , a recent birthday treat for me.  I took far too many photos but many of them would be better taken on firm ground with a tripod rather than hand-held on a rather wobbly boat. So chose to blip this one 
as have photographed this bridge many times but never from this angle. It looks from this like the boat was heading straight towards the bridge support but it did manage to miss it!
