Perkins Discovers Alton's West Seventh Street Is "Steepest Brick Street In World"
ALTON - William Perkins is a proud Marine, but he has now become well-known for something else - the discovery that Alton’s West Seventh Street is the steepest brick street in the world. Perkins has diligently researched the subject for several years and he found that Canton Avenue in Pittsburgh, Penn., has the highest street gradient which is 31.37, but West Seventh in Alton has a gradient that makes it the steepest brick street of any throughout the world, according to his long-time research. Perkins worked with a Principia professor Dr. Marie Farson and her students to measure the steep incline. “Pittsburgh, Pennsylvania brags that they have the steepest street in the country, which is Canton Avenue,” Perkins said. “The gradient on is 31.37%, West 7th is 22.7%. “About one-third of Canton Avenue, though, is concrete and the rest of its cobblestone. West Seventh in Alton is brick - and from my research, that makes West Seventh the steepest brick street
