The Burnley Tunnel is a tollway tunnel in Melbourne, in Victoria, Australia, which carries traffic eastbound from the West Gate Freeway to the Monash Freeway. It is part of the CityLink Tollway operated by Transurban. Running under the Yarra River and the inner suburbs of Richmond and Burnley, the tunnel provides a bypass of the central business district.HistoryThe tunnel was constructed between 1996 and 2000 by Transfield–Obayashi Corporation Joint Venture. Prior to its opening to traffic, the tunnel was opened to the public to walk through from Southbank to Burnley, on 16 December 2000.The tunnel was opened to traffic on 22 December 2000. In February 2001 it was found that a wall panel was cracked with 5 litres of water a second entering the tunnel. The cause was later found to be floor sections lifting from water pressure, and modifications to correct this being approved in November 2001. Also in 2001 Transfield Obayashi Joint Venture agreed to pay Transurban $157 million in damages in an out-of-court settlement over late completion of the tunnel.Transurban launched further legal action against the Transfield Obayashi Joint Venture in 2007, after radar tests indicated the tunnel walls were thinner than that specified in the contract, possibly resulting in the tunnel not lasting for the proposed 100-year design life. Further tunnel leaks were also discovered in 2007, but were unrelated to the tunnel fire. When Transurban hands the tunnel over to the Victorian government in 2034, after 34 years in service, it must do so with the tunnel in the condition that it will have a 66-year operational life.
