In 1982, O'Hare officials unveiled the O'Hare Development Plan, a plan to expand the airport with a new international terminal (now called Terminal 5), and an expansion of the domestic terminals. The new international terminal, located away from the domestic terminals, necessitated the creation of a people mover to allow for connections between domestic and international flights. The system was also intended to provide connections to distant parking facilities. The City of Chicago first awarded the contract for the people mover system to Westinghouse Electric, the second lowest bidder, in 1985. After simplifying their initial proposal in response to concerns from City, the contract was re-awarded to low bidder Matra. Ground was broken in 1987 by Mayor Harold Washington, who also died that year. The system ultimately opened in May 1993.
