I-590 is a tertiary spur interstate route of Interstate 90 through the eastern side of the city. It is 5.07 miles in length, and stretches from Interstate 390 in Brighton through Interstate 490 near Winton Road. Its intersection with 490 was affectionately called the Can of Worms long ago, due to the complexities of two thru expressways, a couple arterial roads, and a major rail route meeting in a poorly-planned and executed way.
Following its terminus as an Interstate at 490, it continues north as a State Route, getting weirder and weirder the farther north you go, until eventually you reach a swing bridge at the outlet of Irondequoit Bay.
