This is a pic I took on the way home from work one night. I always felt shivery when I reached a certain part of the bridge, so I took pics and I got this. There was nothing on the other pics I took before or after this particular spot. It was a cool dry night.
I was walking, and there was no traffic on the road. It is a very remote area, so not many vehicles about. I have no idea what the light is. There is no lighting on the bridge so, I can only think that it is something to do with the flash. I wish I had taken another pic now, to see how far across the road it went lol.
