==State Route 204A== thumb|right|The entire length of Ohio State Route 204A '''State Route 204A''' is a 0.49-mile<ref name=destapeFAI/> alternate route connecting I-70 with SR 204 in Pickerington. Route 204A runs south from I-70 to SR 204, connecting the two parallel roads. Route 204A also serves as the off ramp for I-70 until it becomes Taylor Road and intersects SR 204. A No Outlet sign is posted because the I-70 off ramp is southbound only and there is no access northbound to I-70.
