Getting to Argonne

Getting to Argonne

If using a GPS visitors are recommended to enter location text as “Cass Avenue and Northgate Road, Lemont, Illinois” in order to reach the Argonne Information Center at the Main Gate entrance. Otherwise you may be directed to alternate gate entrances which are controlled-access.

Please Note: There is currently construction on site resulting in road closures. Alternative routes may need to be taken. See Argonne Site Map on Overview page for location of closure

By Car

Argonne is easily accessible by car or public transportation from downtown Chicago, as well as from Chicago's two airports.

Chicago Midway International Airport is the closer of the two airports, located approximately 17 miles away. To reach Argonne from Midway Airport, take Cicero Avenue north to I-55. Enter I-55 south and continue for about 12 miles to Cass Avenue. Exit south on Cass Ave (exit 273A) and turn right at the Argonne sign on Northgate Road, immediately south of I-55. Follow Northgate Road to the Argonne Information Center.

O'Hare International Airport is located approximately 25 miles from Argonne. To reach Argonne from O'Hare Airport, take I-294 south to I-55. Exit south on I-55 (toward St. Louis) and continue for about 5 miles to Cass Avenue. Exit south on Cass Ave (exit 273A) and turn right at the Argonne sign on Northgate Road, immediately south of I-55. Follow Northgate Road to the Argonne Information Center.

Arriving on site with a driver

Every person entering the Argonne site must show photo identification and be badged. If you are utilizing a transportation service where you have a driver (uber/lyft/limo/taxi), your driver will be required to provide a photo ID and obtain a gate pass. If your driver is not comfortable with this, you may have to walk from the gate to the guest house (approximately a 15 minute walk).  Because of this, we recommend the following companies that are familiar with Argonne's policies:

A1 Limouisine (630) 833-3788, option 2
United Limouisine (630) 969-3865
American Taxi (847) 673-1000
