View of Sixth Avenue between Webster Avenue and Wylie Avenue during the hump removal project. The businesses the People's Loan Office and F. Bonavoglia are visible, as are billboards for Silver Top Beer and the Chamberlain Co. Sanitarians. 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.
