There are seven oases located on the Illinois Tollway System. All of the oases span the roadway except for the DeKalb Oasis which is off to the south side of the road.
Signs alert motorists ahead of time as to what facilities are available.
The oases are accessible from either direction and people may walk back and forth from one side to the other. However, there are no facilities for turning around and returning in the direction from which you came. Although the oasis property is owned by the Tollway, it is leased by the fast food restaurant that manages the facility and all other vendors sublet space from these restaurants. All gas stations are managed by Mobil Oil and prices are regulated by the Tollway to be in accordance with local gas prices. All oases have restrooms, fax machines and telephones including TTY phones for the hearing impaired.
