Someone traveling from Denver to Winter Park would take I-70 up into the mountains and then turn off at US 40 and go over Berthoud Pass. Winter Park is at the foot of the pass on the west side, while the turn-off from I-70 is at the foot of the east side. There's a great shot of Berthoud pass on Google Earth. At 39 deg 48' 17.45" N and 105 deg 46' 21.65" W, I clicked off the right-hand side of the road and was quickly 100 to 200 feet below the surface of the road. That's also near the start of a double hairpin. Berthoud doesn't have anything more than guardrails, either.
I found an image of part of the east side of the pass:
And here's the link to a really great shot of most of the west side leading down to Winter Park:
