I wonder what some of the walls around Austin measure, just for comparison. I've been up (marked with county signs) 25% before, and steeper than that by my eyeball judgement.

I dig riding up crazy steep stuff.

I'm trying to get a mental image of these streets. The steepest I've ever seen were Taylor and Fillmore in San Francisco and I've ridden 20% on the road and who knows what on the dirt. I can only imagine sustained climbs of 30%.

Cali is steep.
I wonder what their criteria were -- for example, did the street have to be of a certain length? There is a "wall" on South Grand Street in Downtown LA between 5th Street and 4th Street that doesn't have steps, but should.

Hokie will be proud that there are two streets in Pittsburgh on this list.

I hypothesize that the reason so many of those streets are in California is because only Californians are crazy enough to construct streets, houses and buildings on the slopes of those steep hills. Everyone else has more sense than to do something like that.

That pic of the hill doesn't scare me much, if it were longer I'd cry like a little orphan trying to climb it probably.

if you calculate that first one in HI the grade comes out to 25.23%. grade = (rise/run)*100% right? (800/(0.6*5280))*100%=25.23% and if you want to get all technical the run=sqrt((0.6*5280)^2-800^2) = 3065.32 which results in a grade of 26.1%

I've both walked and driven Waipio Rd. It's f*cking crazy how steep it is.

Here's a pic of Girlygirl standing on it with the horizon "corrected."

Fargo is much steeper than Grand.

I've driven it as well, but I don't think it's 45%. I'll have to find my Big Island book and see what they say.

See my post above, given the elevation change and length they show on the picture it's at most 26.1% might be steeper in spots but not average.

I've been up and down that road. We were in a four wheel drive. I thought we were gonna tip over backwards, roll down the embankment and die in a fiery crash.

We didn't.

It looks like they are using the maximum instantaneous grade, which is a somewhat dubious measure. For example, a steep parking lot ramp would probably qualify for the list based on this metric. For Waipio Road, this page gives an average grade of 25% and "said to be up to 45% at some points" which is hardly conclusive wording.

I'll take your word for it. But, several times I stayed at the Biltmore or Checkers and had depositions at the Wells Fargo building (333 South Grand). I cursed the Grand Street hill every time when I waked up it. That I was carrying a large brief case full of documents and wearing dress shoes, a suit and tie probably did not make the walk any easier.
