State Route 88 is a highway generally running in an east–west direction in the northeastern portion of the U.S. state of Ohio. Its southern terminus is in Portage County at SR 59 at the intersection of Freedom Street with Main Street in Ravenna. SR 88 is labeled north-south southwest of U.S. Route 422 (US 422) and SR 168/SR 528, and labeled east-west east of there. SR follows a northerly direction for a little more than one mile (1.6 km) along Freedom Street, to the SR 14 and SR 44 concurrency bypass. From here, the route heads in a northeasterly direction. Its next intersection is with SR 700, at the southern terminus of the latter route. One-quarter mile (0.40 km) further to the northeast, SR 88 joins SR 303 for about one-half mile (0.80 km). SR 88 then continues northeast, crossing over Interstate 80 and the Ohio Turnpike, before turning due north as it enters Garrettsville. Here, as South Street, the route intersects SR 82, then becomes North Street before exiting the corporation limits.
