CINCINNATI (AP) — Ohio plans a $34 million renovation to a downtown Cincinnati tunnel in a project that could jump-start the overhaul of a historic park, and attract new restaurants, apartments, and condos.

Officials with the Ohio Department of Transportation told The Cincinnati Enquirer (http://cin.ci/RuhYXg ) that the state plans to start work in spring 2014 to install new ventilation, lighting and tiles inside Lytle Tunnel, which takes drivers on Interstate 71 underneath Lytle Park in the eastern part of downtown Cincinnati.
