The speed limit changes from 25 to 55 MPH at the bottom of the hill. Total hill height is 140 feet, so no chance for a running start and DWL techniques.
I guesstimated the grade at 6%. It's steep and high enough that the DOT put a steep hill sign at the top.
Just for grins and giggles, I plugged a 6% grade into the drag equation from my coastdown test. The theoretical coasting speed in neutral on a hill of that slope long enough to reach full speed, at the same temperature as the coastdown test, is 84 MPH. That speed would be faster on a warm day.
When I drive that hill in the other direction (downhill), I try to EOC so as to top the hill at 25 MPH. I'm up to 55 MPH when I apply brakes for the speed limit change.
