"Top 10 U.S. Steepest Streets" calls out Pittsburgh's brutal Canton Avenue. It clicks in at 37 percent gradient.
Any cyclists out there want to take on what Lance Armstrong has deemed the "steepest climb I've ever seen on a bike"?
Then buy a ticket to for Hawaii and pedal to Waipio Valley Road, a short but tortuous climb of 800 feet in six-tenths of a mile. With sections slanted at a 45-
degree percent grade, and access given only to cars with 4-wheel drive, just looking at the muscle-shredding lane can make rivers of sweat start to flow. As Armstrong said: "You know it's steep when the people walking down are walking backward."
This fearsome cliff road gets top billing on "Top 10 U.S. Steepest Streets," a ranking of terrible hills for cyclists created by Fixr and recently featured at Urban Velo. The run-down contains some challenging claims for folks who think America's worst hills are located in San Francisco or perhaps the Rockies. The second-slantiest street, for instance, is said to be Canton Avenue in Pittsburgh. It is the "steepest public street in the United States," writes Fixr, "only second steepest in the Guinness Book of Records because of a mistake in calculations (1st is Baldwin St. New Zealand, thought to have been 38% but is actually 35%)."
Number eight in is the Steel City, too.
