State Route 21 (SR 21) is a north–south state highway in northeastern Ohio. The southern terminus is north of StrasburgonU.S. Route 250. The northern terminus is at an interchange with Interstate 77inCuyahoga Heights.
The southern terminus of SR 21 is on US 250inFranklin Township, Tuscarawas County, north of Strasburg and about 3.1 miles (5.0 km) north of I-77 exit 87. At the intersection, westbound US 250, which had been heading north–northwest, turns to the west while its roadway continues as SR 21. The route is an undivided, two-lane road.
SR 21 proceeds through Franklin Township. At the line with Bethlehem Township, Stark County, the route crosses SR 212 (Dolphin Street SW) and takes the name Erie Avenue SW. As the route enters Navarre, it takes on the character of a small-town street, taking the name Main Street, then enters a concurrency with US 62 at Canal Street. As the route continues through Navarre, it begins to pick up turn lanes. In northern Navarre, the route becomes three lanes, adding a center left-turn lane. The route next proceeds north into the city of Massillon, becoming a four lane controlled access highway at an interchange with US 30 and takes Interstate 77 Alternate status from it. SR 21 crosses SR 172 (Lincoln Highway) in downtown Massillon and SR 236 (Lake Street) near the northern city limit. The route continues north crossing SR 93 near Canal Fulton.
SR 21 later crosses into both Summit County and Norton. Just after, there is an interchange with SR 585 and Wooster Road that has an unusual configuration. It is a hybrid combination interchange with a left-hand flyover ramp from eastbound SR 585 to northbound SR 21. Eastbound Wooster Road just west of the interchange crosses the ramp from eastbound SR 585 to southbound SR 21at-grade and merges with the loop ramp from southbound SR 21 to eastbound Wooster Road. Additionally, Wooster Road leads to Barberton.
SR 21 merges onto I-77 (exit 136) in Copley Township west of Akron, dropping the assignment of Interstate 77 alternate. It remains in a concurrency with the interstate until reaching exit 145 in Richfield, where it departs the interstate. SR 21 next passes under the Ohio Turnpike. It then passes through Brecksville and into Independence, where it crosses Interstate 480 on an overpass immediately east of I-480's interchange with I-77. It next passes briefly through Valley View and into Cuyahoga Heights.
In Cuyahoga Heights, SR 21 reaches its northern terminus at I-77 exit 157.
SR 21 follows the route of the old U.S. Route 21, a major north–south highway that connected greater Cleveland, Ohio, to southern South Carolina. South of Strasburg, Ohio, near the current southern terminus of SR 21, the designation of US 21 was moved to the new Interstate 77 freeway in east-central and southeastern Ohio by the early 1970s and then decommissioned. North of Strasburg, what remained of US 21 as a route separate from I-77 became SR 21.
While I-77 directly serves the larger cities of Canton, Akron and Cleveland, SR 21 connects the smaller communities of Massillon and Norton (and indirectly Barberton), and serves some Akron and Cleveland suburbs as a local through route.
Very heavily traveled before the Interstate era, much of SR 21 is divided highway or even freeway.
All exits are unnumbered.
