Diamond Street at Ross Street looking to Grant Street showing hump cut progress near the Allegheny County Courthouse. The "hump" cut took place in the area of Downtown 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.
