View of Diamond Street looking east from Grant Street showing progress on the "hump" cut. Visible on the left is the Court House, and in the background is the Pittsburgh Academy building, forerunner to the University of Pittsburgh which was at this location from 1855-1882. The "hump" cut took place in the area of Downtown known as Grant's Hill. The project began in 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.
