The proposal to build CityLink was first announced in May 1992 and received the State Government's formal approval in mid-1994. The contract was awarded in 1995 to a consortium of Australia's Transfield Holdings and Japan's Obayashi Corporation, which then formed Transurban. The total value of the project was estimated in 1996 at about $1.8 billion, and the concession to operate the road was initially due to expire in 2034. This concession has since been extended, and is now due to expire in 2045.
