A4B to the main A concourse. Expansions were completed in the spring of 2010. Privatization attempts Chicago has considered privatizing the airport, but the deals fell through in 2009 and 2013. On April 20, 2009, a $2.5 billion deal to privatize the airport via a 99-year lease fell through when the consortium could not put together financing. The city would have kept $125 million in the down payment. The consortium operating under the name of Midway Investment and Development Company LLC consisted of Vancouver Airport Services, Citi Infrastructure Investors, and Boston's John Hancock Life Insurance. It was awarded the contract in October 2008 by the City Council, which voted 49–0 to approve it. The consortium would have operated the airport and collected airport parking, concession, and passenger facility charges. However, Chicago would have continued to provide fire and police services. In 2010 a new slogan emerged, calling the airport "The busiest square mile in the world". In September 2013, Mayor Rahm Emanuel terminated new negotiations to privatize the airport, noting that the process was no longer competitive after one of the two finalists had backed out. The one remaining was Great Lakes Airport Alliance – a partnership of Macquarie Infrastructure and Real Assets and Ferrovial. Macquarie was one of the investors in the Chicago Skyway. The group that had backed out was a group that included the Australia-based Industry Funds Management and Manchester Airports Group. The Great Lakes proposal had been valued at $2 billion and would have involved a 40-year lease. Modernization program Construction began in 2018 on expansions of the security checkpoint and main parking garage. The bridge spanning Cicero Ave is being widened from 50 feet to over 400 feet, allowing up to 17 security lanes and a streamlined queue. As the current terminal opened just a few months prior to the September 11th attacks, the security area was quickly rendered too small for the new screening measures and subsequently was forced to expand inward, taking away from space in the concourses. Space that is reclaimed by moving security outward into the bridge will be redeveloped with an expansion of the central food court. The main parking garage is being extended eastward over the CTA L tracks to add 1,500 spaces and streamline the entrance way. In addition to the redeveloped central food court, new concession options will open in phases including a food court in Concourse
