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).

Where is that? I want to make sure I avoid it.

I've seen those signs before in eastern Tennessee between Chattanooga and Nashville, and also in Pennsylvania around Bethlehem. I know when the number's above 10, it's pretty friggin steep. I was also driving a moving van through Kentucky one time and couldn't maintain 30 MPH on the interstate on an incline.
Of course, I live in a place where you can park in neutral and not set the parking brake and your car will probably not move an inch.
