# Ohio State Route 84

State Route 84 (SR 84) is an east–west state highway in the northeastern portion of the U.S. state of Ohio. Its western terminus is along US 6 at US 20 in Euclid, and its eastern terminus is at the Pennsylvania state line about 10 miles (16 km) south-southeast of Conneaut; Pennsylvania Route 226 continues eastward.
A portion of SR 84 runs along the historic Johnnycake Ridge Road. SR 84 is not signed between US 20 and the eastern end of US 6 concurrency.

## History

Route 84 was established in 1923 and originally ran from 1-mile (1.6 km) south of Madison to 2 miles (3.2 km) west of Andover along the current alignment of State Route 307; from 1-mile (1.6 km) south of Madison to Dorset; and from Dorset to West Andover. It was expanded in 1926 to Willoughby Hills along a previously unnumbered road. In 1931, the route was truncated at Dorset and Dorset to West Andover was decertified. In 1935, Route 84 was rerouted from Madison to Ashtabula along the previous State Route 307 alignment, which was unnumbered before 1933. The former alignment from south of Madison to Dorset was certified as State Route 307. In 1938, it was extended to the Pennsylvania state line along the former alignment of State Route 83 from Ashtabula to Kelloggsville, which was unnumbered before 1926, and along a previously unnumbered road from Kelloggsville to the state line.
