Wylie Avenue Hump Cut

View of hump cut progress along the north side of Wylie Avenue, looking east from the corner of Sixth Avenue featuring David M. Kinzer Leather and Findings, N. Schwartz Jr. Tinner, B. De Grazoa, and the Pittsburgh Loan Office. The "hump" cut took place in the downtown area known as Grant's Hill. The project began with planning in 1909 and ended with the final cut in 1913. It changed the gradient of Grant Street, Diamond Street, and Oliver, Fifth, Sixth, Webster and Wylie Avenues.
