By December 2004, a set of changes to the CCT were required. The RTA accepted responsibility for the costs, totalling $38.1 million. Believing it was constrained by 'no net cost to government', the RTA negotiated a solution with CCM. CCM would carry out the bulk of the changes at their cost and the RTA would allow CCM to charge a higher toll. The RTA met the other $3.1 million from the upfront payment (as covered in Chapter 2).
