Office of the Inspector GeneralSeal of the Illinois State Toll Highway Authority

The Office of the Inspector General (OIG) for the Illinois Tollway was created to maintain the public's trust in the administration and operation of the Illinois Tollway. The Inspector General is empowered to root out and fairly investigate all instances of waste, inefficiencies, fraud, corruption, and mismanagement in the day-to-day operations of the Illinois Tollway.  


About the Office

Mission Statement

The mission of the OIG is to ensure integrity and accountability in the day-to-day operations of the Illinois Tollway by conducting fair and thorough investigations into reports and allegations of waste, inefficiencies, fraud, corruption, mismanagement and misconduct. To this end, the OIG shall investigate complaints, allegations, or actions evidencing violations of law, rule or regulation, abuse of authority, gross or aggravated misconduct, or misconduct that may be criminal in nature, by Board members, executive management, senior staff, and all other employees (collectively, "Tollway employees"), contractors and/or vendors of the Illinois Tollway.


The jurisdiction of the OIG extends to Tollway employees, contractors, and vendors. As a general rule, the OIG does not become involved in cases involving private disputes, labor-management issues, or litigation. Matters investigated by the OIG may also fall within the jurisdiction of other agencies (i.e., Illinois State Police, District 15, other law enforcement investigators, prosecuting authorities, Office of the Executive Inspector General, other inspectors general, etc.). In such cases, the Inspector General may make a referral to or work together with other agencies to investigate complaints.


Periodically, a report of the OIG's activities (i.e., new, pending, and concluded investigations, complaints, referrals, internal control evaluations, etc.) shall be provided to the Governor's Office and the Chairman of the Board of Directors of the Illinois Tollway. The report may include recommendations for the Illinois Tollway to consider in addressing and avoiding the recurrence of any violations uncovered by the investigation. When appropriate, a report of investigation may also be forwarded to a prosecuting agency for review to determine whether the underlying facts are sufficient to support a criminal prosecution.


Due to the confidentiality of the matters under investigation, complainants are not normally apprised of the progress of investigations or reviews and may not be informed about the disposition of an investigation or review.

Records of ongoing investigations of the OIG are not public records.

It is the general policy of the OIG to neither confirm nor deny the existence of an investigation or review prior to disposition of the matter by the Inspector General.

Public employees are subject to whistleblower protection.
