I'm assuming you're talking about the featured image for the post.

What you're seeing is not uncommon in America, especially in the mountains. Roads for traffic in the opposite direction can be separated from your road.

It's also often the case that the other road might be on the other side of a hill/mountain. I've seen that in multiple states across the US.

This specific instance, where two separate roads are going in the same direction can occur where the left road doesn't have exits/entrances, and can move faster than the right road when there's traffic. The left road may also be switched to change traffic directions. I most recently saw this in some mountainous terrain in Arizona.
