The Illinois State Toll Highway Authority is an autonomous body, whose members are named by the Governor. The Authority has the power to collect and raise tolls, and are responsible for the maintenance and construction of tollway roads and related signage (including electronic message boards, used for driving time notices, Amber Alerts and other notifications). They also supervise and manage the seven Tollway Oases.

The Illinois State Toll Highways are the only Toll Highways within the United States that accept pennies for toll payment in automatic toll lanes. The reason commonly given for this is that Abraham Lincoln appears on the obverse of the US 1 cent piece, the penny, and Illinois is known as the "Land of Lincoln."
