Hump cut progress at the northwest corner of Wylie Avenue and Sixth Avenue, looking west down Wylie Avenue. At the corner on Sixth Avenue is a large billboard reading "Turkish Trophies 10¢ for 10 with Gift Slip". 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.
