The Ohio River corridor serves as the primary artery for this mid-1970s look at the Tri-State area, where the borders of Ohio, Indiana, and Kentucky converge at the major urban centers of Cincinnati, Covington, and Newport. This survey, revised during the peak of the interstate era, shows the established network of Interstate 75, Interstate 71, and Interstate 74 facilitating movement between industrial hubs like Dayton, Middletown, and Hamilton.
