The students were part of the Summer Youth Employment Program in 2008.
The program was an initiative of the Blagojevich administration. The report shows nearly 3,000 young adults participated.
The program was funded with $7 million from IDOT's roads fund. The fund is made up of revenue from motor fuel taxes and vehicle registrations.
Money in that fund is supposed to go towards transportation projects. And the SYEP was founded to be a transportation-based project.
But records show some young adults listed tasks like moving furniture, conducting surveys, and helping at a local golf course on top of working on road projects like cleaning up highways.
The report from the Executive Inspector General also shows IDOT paid more in wages than were earned. The department is now trying to get about $640,000 back from the service providers who employed the teens.
The report also says the project is the subject of a federal investigation.
