A different view from the Dartford Crossing

On my way into work today there was slow moving traffic on the Dartford Crossing, I'm not so good with heights anymore so hate being stuck on it in the outer lane. To make things worse I was in the Q7 which is slightly higher than the barriers arghhhhhhh!

But the views I got were cool, I could see further down, see more boats/ships and more buildings.

There was a funny looking building with a funny looking chimney right next to the bridge, need to find out what that is.
