I have been staring the Dartford crossing on google maps for a while, trying to figure out how to get close to the bridge to take some photos of it from interesting and oblique angles. I drove to where I thought I could get on to the estuary bank, but it turned out to be private property (an Asda distribution centre) and the second spot I was thwarted, by water ways and fences. Finally I found a way an access path by a supermarket a short way downstream and was able to get underneath the bridge that many time I have crossed either above or below.
