I have a photo of a sign taken at Burgess Junction, WY in "my pictures" showing the grades of Hwy 14 & 14A if I could figure how to get into this irv.2 post.
The important information-
Hwy 14- 5-7% grade, 4600' elevation change in 18 miles!
Hwy 14A- 10% grade, 3600' elevation change in 10 miles!
Hwy 16 is less but still a good pull as the OP says.
We have REAL mountain grades here in the west.
