The expressway continues north through Livingston County to Geneseo, which I-390 skirts to the south and east. While there is no exit for Geneseo on the part of the freeway that encroaches the village, exit 8, an interchange with US 20A east of Geneseo, provides the connection. Also accessible from the junction is the hamlet of Lakeville, situated off to the east at the junction of US 20A and NY 15. I-390 continues on, encountering NY 15 north of Lakeville and southeast of Avon. From here north to Rochester, I-390 and NY 15 follow closely parallel alignments. Both highways meet US 20 and NY 5 east of Avon prior to crossing into Monroe County.
