Demolition of the expressway has been proposed in the past, most prominently by former Australian Prime Minister Paul Keating, who in 1994 offered federal funds in the amount of A$150 million toward such a project. The then NSW Premier, John Fahey, rejected the proposal because of the cost and the resultant traffic problems. In 2005, the cost of demolition was estimated at more than A$1 billion, and the traffic problems resulting from the removal of the link would be severe, given the lack of alternative routes.
