Interstate 590 (I-590) is a north–south auxiliary Interstate Highway that serves the immediate southeastern suburbs of the city of Rochester, New York, in the United States. It extends for from an interchange with I-390 in Brighton to the Can of Worms, a complex interchange connecting I-590 to I-490 (the Eastern Expressway) just inside the Rochester city line. I-590 makes up the southeast quadrant of the Rochester Outer Loop, which continues west on I-390 and north past the Can of Worms on New York State Route 590 (NY 590). The highway is a spur route of I-90; the connection between the two is made via both I-390 and I-490. The portion of I-590 between Winton Road and the Can of Worms was originally constructed in the 1960s and designated as part of NY 47 from Elmwood Avenue northward. In the late 1970s, I-590 was proposed as a designation for the entire southern half of the Outer Loop. Ultimately, it was cut back to its current western terminus at the then-proposed I-390. I-590 was officially assigned in 1980 following the elimination of NY 47, and the last segment of the freeway between Winton Road and I-390 was completed by the following year. ==Route description==
I-590 begins at a semi-directional T interchange with I-390 in the town of Brighton, a southern suburb of the city of Rochester. The route heads east from the junction, passing under South Clinton Avenue (which passes through the east half of the interchange but does not connect to either freeway) and traveling east through open fields to its first interchange (a diverging diamond interchange) at South Winton Road. Here, the surroundings rapidly change from fields to densely populated residential areas as it passes through a more developed section of Brighton. As it approaches NY 31 (Monroe Avenue) at exit 2, I-590 turns a full 90 degrees to the north. Past NY 31, I-590 runs through the former Erie Canal and Rochester Subway bed. The freeway travels due north along this stretch, flanked on both sides by residential neighborhoods separated from I-590 only by sound barriers. Not far to the north of the intersection with NY 31 is exit 3, a partial diamond interchange for Elmwood Avenue permitting access from I-590 south and to I-590 north.〔 Prior to 1980, NY 47 entered the freeway at this point and followed both I-590 and NY 590 north to Sea Breeze.〔 Another partial interchange with Highland Avenue follows at exit 4—making the two connections that exit 3 omits—before I-590 enters the Can of Worms, a complex interchange connecting I-590 to I-490. North of the ramps leading to I-490, I-590 descends northeastward into a cut and passes below both I-490 and NY 96 as it becomes NY 590, which continues onward toward Sea Breeze.〔
