The steepest passenger road in (North America? The northern hemisphere?) is the is the road down to the Athabasca glacier in Jasper Nat'l Park in Canada. The driver informed us that the road is inclined at an average of 45 degrees. I don't remember how long it is, but it looks like it is about 1/2 mile long. There are no bicycles allowed on it, though. More realistically, the toll road up Mt. Washington in New Hampshire is 8 miles long and pitched at an average of 12 degrees, and up to 18 in places. It is the site of a bicycle race once a year or so.
