Raytheon had been contracted to build the system. The project was cancelled in October 1999. Rosemont had been selected in 1993 by the RTA be home to a demonstration PRT system. Five other municipalities in the suburban Chicago metropolitan area had submitted unsuccessful bids to be host to the PRT project.

The project marked the first serious activity related to PRT construction since Morgantown Personal Rapid Transit.
