Ohio State Route 420

State Route 420 (SR 420) is a north–south state highway in the northwestern portion of the U.S. state of Ohio. The southern terminus of this four-lane divided highway is at a trumpet interchange with U.S. Route 20/US 23 (US 20/US 23) approximately 3.25 miles (5.23 km) northeast of the village of Luckey. The route’s northern terminus is at the southern terminus of Interstate 280 (I-280), where the two routes meet the Ohio Turnpike (I-80/I-90) at a double-trumpet interchange nearly four miles (6.4 km) southwest of Millbury. SR 420 made its debut in the late 1960s. It is a major route whose primary purpose is to link US 20/US 23 with I-280 and the Ohio Turnpike.
