The route runs parallel to the Ohio Turnpike (Interstate 80/Interstate 90, I-80/I-90) for much of its length, and intersects the turnpike at exit 13 northeast of Montpelier in Holiday City. US 20 and US 20A are never more than five miles (8.0 km) apart for the entire 50-mile (80 km) stretch through the Ohio farm country, as the mainline of US 20 takes the more northerly route.[3][4]


The current US 20A was designated U.S. Route 20S in 1932, which replaced State Route 271 which had run from US 20 south to Montpelier, truncated Ohio State Route 107, joined Ohio State Route 2, and followed a road formerly not on the state highway system through most of Lucas County. It became US 20A in 1935. US 20A was moved to its current location along SR 15 from State Routes 576 and 107 in 1964. (107 then reclaimed some of the miles that had been taken from it in 1932.)[2] In the 1950s, part of the road east of Swanton was abandoned to make way for the Toledo Express Airport.
