You might try looking at Google Earth until you find a place that suits you.
Many years ago my family took a trip where we travelled around the Black Canyon area. We travelled around on a winding two-laned highway at the edge of a cliff. The highway had been opened for only a few weeks, even though it was the middle of the summer; it took that long to repair it after the previous winter. We kept seeing signs that said the left lane was closed ahead. When we got there we would see that the left lane had slid down the side of the mountain. After hours of this, we saw a sign that said the right lane was closed. We all panicked but continued driving seeing how we had no other choice. We found that the mountain had slid down under the road until the road buckled upward. At one point we looked down and saw something straight and white at the bottom. Dad admitted that was the freeway that most people took, but he wanted to show us the scenic view of beautiful Colorado. I can't find it on Google Earth, but it's possible that it either has been changed in the last twenty years or that I remember it wrong. Maybe it was state highway 92. Anyway, it's closer to Crested Butte than it is to Denver.
