The entirety of SR 814 lies within Champaign County.

The southern terminus of SR 814 is at U.S. Route 36 (US 36) approximately three miles (4.8 km) east of Urbana, and its northern terminus is at SR 296 about five and a half miles (8.9 km) northeast of Urbana.

SR 814 commences at the intersection of US 36 and Ludlow Road east of Urbana in Union Township, just a short distance west of Urbana Country Club.

The highway trends northwesterly for its entire length through farm country, passing by a few homes along the way.

It was discovered that because the number 714 was also a slang term for Quaaludes, a prescription drug often used recreationally, young persons were stealing the highway signs.
