Ross Street Hump Cut

Ross Street at Fifth Avenue looking to Diamond Street, with a view of the Bridge of Sighs connecting the Allegheny County Courthouse and Jail, during the "hump" cut. In the 1900s, 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.
