Ohio State Route 662
State highway in central Ohio, United States
From Wikipedia, the free encyclopedia
State Route 662 (SR 662 or OH 662) is a north–south state highway located in the central region of the U.S. state of Ohio. The route functions primarily as a rural connector, linking State Route 209 and State Route 93 while providing access to agricultural land, isolated residences, and local road networks across three counties.

The highway extends for 8.18 miles (13.16 km), beginning at its southern terminus at a T-intersection with State Route 209 approximately 5.50 miles (8.85 km) northwest of the city of Cambridge. Its northern terminus is located at a T-intersection with State Route 93 roughly 3.50 miles (5.63 km) south of the village of Plainfield. Throughout its entire length, SR 662 remains a two-lane, undivided roadway and does not pass through any incorporated municipalities.
Route description
State Route 662 begins in a rural section of western Guernsey County characterized by gently rolling terrain, farmland, and scattered woodlots. From its southern terminus, the highway proceeds northward with a generally straight alignment, punctuated by mild horizontal curves that follow the natural topography of the region.
After a short distance, SR 662 crosses into the extreme northeastern corner of Muskingum County. This segment is brief, extending less than a mile, and continues through sparsely populated countryside with no significant intersections, developments, or changes in roadway character.
The route then enters southeastern Coshocton County, where it maintains its rural setting. Land use along this section consists predominantly of agricultural fields, wooded tracts, and isolated homesteads. Access points are limited to local roads and private driveways. As SR 662 approaches its northern terminus, traffic volumes increase modestly due to connectivity with State Route 93.
State Route 662 does not include passing lanes, grade-separated interchanges, or urban infrastructure. The highway is not part of the National Highway System, a network of roadways identified as critical to national defense, economic activity, and interregional mobility.[2]
Traffic and usage
SR 662 primarily carries local traffic, including passenger vehicles, agricultural machinery, and light commercial trucks. Average annual daily traffic (AADT) counts are relatively low compared to urban and suburban state highways, reflecting the route’s rural context and absence of major population centers.
The highway serves as a practical link for residents traveling between rural properties and nearby regional routes, particularly SR 209 and SR 93, which provide access to Cambridge and other communities in central Ohio.
Engineering and maintenance
State Route 662 is maintained by the Ohio Department of Transportation. The roadway consists of asphalt pavement with paved shoulders and standard lane markings. Drainage infrastructure, including culverts and roadside ditches, is present along much of the route to manage surface runoff from adjacent farmland and wooded areas.
Safety features include regulatory and warning signage, reflective pavement markings, and guardrails at select locations. The highway generally conforms to ODOT rural highway design and safety standards, with improvements implemented periodically as part of statewide maintenance programs.
History
State Route 662 was established in 1937 during a period of systematic expansion and formalization of Ohio’s state highway network. The designation was intended to improve north–south connectivity between existing routes and to support transportation needs in rural central Ohio.
Since its inception, SR 662 has retained the same general alignment and termini. Unlike many state routes that have undergone extensions, truncations, or major realignments, SR 662 has experienced minimal structural change. Modifications over time have been limited to routine resurfacing, signage upgrades, and minor safety enhancements.
Future
As of 2025, no major reconstruction, widening, or realignment projects are planned for State Route 662. Anticipated future work is expected to consist of routine maintenance, pavement preservation, and localized safety improvements as required.
Major intersections
The entire route is located in central Ohio.
