The Cross City Tunnel is a 2.1-kilometer-long tunnel located in Sydney, Australia. It links the western fringe of the central business district (CBD) to the eastern suburbs. The project was a public-private partnership intended to design, build, finance, and operate the tunnel that would charge users a toll. The concession was awarded to Cross City Motorway Ltd, composed of Cheung Kong Infrastructure Holdings, DB Capital Partners, and Bilfinger Berger. It reached financial close on December 18, 2002, and opened for traffic in August 2005. However, traffic through the tunnel never reached the levels forecast and after December 2006, after little more than a year, the company was insolvent, with debts of over $A 500 million. In June 2007, Leighton Contractors and ABN AMRO acquired Cross City Tunnel group for $A 700 million.
