Quite long parts of the Karakoram Highway look like this well-kept new road. But there are some sections that make driving very difficult with huge pot holes and constant landslides. Unfortunately I haven't got any photos of those bad stretches of road as I just happened to travel those at night.
Hello Erling, using PSE10,
1. I cropped your photograph from the left and extended it to the right.
2. Then I copied ans pasted the blue b/g into the new space.
3. I used the clone tooland the spot healing brush to help remove the joining lines.
