View of the Hump District on Strawberry Way from Pentland Street to Grant Street. During the 1900s, 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.
