Directions from O'Hare International to Argonne National Laboratory

• Drive east (toward Chicago) on Interstate 90 to the exit for Interstate 294 south (toward Indiana).
• Go south on I-294 to the exit for Interstate 55 south (toward St. Louis).

294 is a toll road, so you will change for the automatic lanes. Alternatively, if you do not have exact change, you can use the manual lanes with a live toll taker.
• Take I-55 south to the South Cass Avenue exit (Exit No.273A).
• Turn left, after you exit I-55, to drive over the overpass. At this point you will see the sign for Argonne National Laboratory.
• Turn right onto Northgate Road, which is the Argonne entrance.
• Follow Northgate Road to the Argonne Visitor Center.
