Chicago is accessible by several interstate highways. The city is approached from the northwest by I-94, which merges with the John F. Kennedy Expressway and the Dan Ryan Express-way, traversing the city north-south before turning into the Calumet Expressway heading south out of (or into) the city. To the west, I-294 rings much of the Greater Chicago area, turning into the Tri-State Tollway further south and intersecting I-290, which runs east-west, becoming the Dwight D. Eisenhower Expressway into the heart of the city. I-55 leads to Chicago from the southwest, turning into the Adlai E. Stevenson Expressway.
