The other side of the road

I found an M6 underpass, rather overgrown with brambles, hence the grazes on my hand.  It goes alongside a stream that has had to be allowed for when the M6 was constructed.  Thousands of vehicles travel over this every day, and I'm sure none are aware of this nod to nature - it doesn't even appear on detailed maps.  
This is how my new office looks from the other side of the road.
