I'd prefer an actual GPS log that will show me what the actual grades are. I doubt very much that they are over thirty percent for even very short distances.Look, I don't know enough of the math to give you a precise measurement, but use those triangles as a visual reference for incline. I assure you, it is the reality here. Thank god I'm riding on paved roads.
Failing that, can you give me the names of the streets, the nearest town, and precise GPS coordinates (latitude and longitude) and I can go look for myself?
The steepest paved road grade in the United States is disputed, but some of the steepest roads in the country include:
- Canton Avenue, Pittsburgh, Pennsylvania: This street in the Beechview neighborhood is considered the steepest officially recorded public street in the United States. It has a reported 37% grade, meaning that for every 100 feet traveled, you gain 37 feet in elevation. However, the Guinness Book of World Records lists Baldwin Street in Dunedin, New Zealand as the world's steepest street.
- Waipio Valley Road, Honokaa, Hawaii: This rural road has sections with a 45% grade and is closed to non-local traffic.
- State Route 108, California: This highway runs through the Sierra Nevada and has a maximum grade of 26%.
- Interstate 84, Oregon: The stretch of this highway in the Blue Mountains, known as Emigrant Hill or Cabbage Hill, has a 6% grade and gains 2,000 feet of elevation in 6 miles.
- Eldred Street, Los Angeles, California: This street has a 33.30% grade.
- 28th Street, Los Angeles, California: This street has a 33% grade.
- Baxter Street, Los Angeles, California: This street has a 32% grade.
I agree that the 108 in the Sierras is wicked steep and bluntly pretty scary.
