View of Clay Alley during the hump removal project, looking north from Chatham Street. 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.
