 When US 6 was routed into Ohio in 1932, it was routed via the stretch of SR 85 between Euclid and Andover.For the six years following, US 6 and SR 85 were run concurrently along that stretch of roadway.By 1938, SR 85 was truncated to its current routing between Andover and the connection to Pennsylvania Route 285 on the Pymatuning Causeway, leaving US 6 to be the lone route running between Euclid and Andover.
