Interstate 77 replaced U.S. 21 from West Virginia northward to Cleveland. Portions of original U.S. 21 remain within the state route system as Ohio 21, including a shared alignment with the freeway through south Cleveland.
Interstate 77 would have continued directly to the Cleveland Memorial Shoreway had Interstate 90 been routed along the freeway as originally envisioned. As it was, the Shoreway's west end was never constructed and Interstate 90 was rerouted southward around downtown, ending Interstate 77 at its present location.
