I am looking for the maximum gradient (slope - elevation/horizontal distance) that you have seen. What city is it located and if you are able, how big is the road (ie.: local, collector, freeway,...)

Typically the maximum grade is 15% which is a bit less than 1:7.

I'm not sure what the gradient of it is, but Lake Ave in Duluth, MN is really steep. It must go up close to 85 feet in 8 blocks! It's a local surface street.
After it snows, the plows can only go DOWN the road! They have to go up somewhere else and traverse over. Most of the avenues in Duluth are pretty steep since they run away from Lake Superior, but Lake Ave sticks out in my mind as one of the steepest for the longest stretch.

A three block section of Filbert Street in San Francisco is supposed to have a slope of 1.7 to 1 (h to v).

There are alot of steep ones in San Fran.
There is also a very steep mountain pass in Smugglers Notch Vermont. it's only open during the summer months because it becomes impassable during winter.

I always thought Lombard Street in San Fransisco was the steepest grade in the US.
It is just "stupid steep". Usually, when you see a hill that steep, it is covered in snow and marked with double black diamonds on a sign at the top....

I have no idea, but I was on some really steep ones in San Francisco, small city streets.

I think I read somewhere once that the maximum possible was 45 degrees....
