Slang term for the westernmost interchange on the Eisenhower Expressway (I-290) in Chicago. Three lanes of Interstate 290 narrow to two and three lanes of Interstate 88 narrow to one, to form three lanes of the Eisenhower. The "strangling" effect of merging two three-lane freeways into one three-lane freeway often creates huge traffic jams, thus its notoriety as the "hillside strangler."
