For comparison, and I'm sure you drove it, the natural grade of Lombard St is 27% but the effective grade is 14% to 16%.jasonh300 wrote:fvwazing wrote:14% means the road drops 14m if you drive 100m. That is pretty steep.
What is that in feet? j/k
Yes, that's pretty steep. I did some research and the steepest grade on the U.S. Interstate system is 8%, and I have driven it (I-24/US-41/64 Westbound over Monteagle Mountain, TN).

I imagine it would be 45deg where rise=run. Or run=fall.
