I found some photos on the web that I have good reason to believe are of the road between Tikrit and Kirkuk. Colin Freeman described the road in his book, Curse of the al Dulaimi Hotel. From page 136:
[A local Iraqi police chief] directed us to the spot where Kirk had vanished. It was near the brow of a long, winding hilltop road, miles from anywhere and surrounded by rocky outcrops. A long way from any help if you got yourself in a tight spot. At the bottom of the other side of the hill, there was a US Army checkpoint, where Dawkins had handed over a copy of Kirk's photograph.
