SJ3389 : Queensway Road Tunnel, River Mersey
taken 11 years ago, near to Birkenhead, Wirral, England

Queensway Road Tunnel, River Mersey
There is an optical illusion of appearing about to go uphill. I was actually going downhill, approaching the bottom of the tunnel, from the Birkenhead side of the river. The change in gradient is, in reality, onto flat ground underneath the middle of the River Mersey.
