New York State Route 390 (NY 390) is a north–south state highway located along the western edge of the city of Rochester, New York, in the United States. The route, a limited-access northward continuation of Interstate 390 (I-390), extends for 8.00 miles (12.87 km) from I-490 in Gates to the Lake Ontario State Parkway in Greece, less than 1 mile (1.6 km) from the Lake Ontario shoreline. Between I-490 and NY 104, NY 390 makes up the north–south segment of the northwest quadrant of the Rochester Outer Loop, a series of expressways encircling Rochester. At NY 104, the Outer Loop departs NY 390 and follows NY 104 east into the city.
The freeway was constructed in stages from the 1960s to the 1980s, with the first segment—between I-490 and NY 31—opening to traffic c. 1963. At the time, it was part of NY 47, which followed the completed portions of the Outer Loop from Gates to Irondequoit. An extension of the freeway north to U.S. Route 104 (US 104; now NY 104) was opened to traffic in the early 1970s. NY 47 was eliminated in 1980, giving way to NY 390 from I-490 to NY 104. NY 390 was extended to its current length in the early 1980s.
