The Northwestern “corner” of I-270 has a cloverstack interchange with US 33/SR 161. It then makes a sharp right as it heads towards Worthington. In Worthington are the notoriously congested interchanges of three major roadways, State Route 315 (SR 315), US 23, and I-71. This is the location of the recent North Side Mega-Fix, which fixed the heavy weaving section between US 23 and SR 315, however the project also worsened weaving between US 23 and I-71, leading to frequent mile-long backups.
