On 29 September 2014, Napthine along with former Minister for Public Transport and Roads Terry Mulder signed what was reported to be a $5.3 billion contract with the now defunct East West Connect consortium to build the controversial East West Link toll road. He has since received a lot of criticism for this, not only for his decision to sign on the eve of the month-long caretaker period before the upcoming November 2014 state election and before two legal cases into the planning approval for the project were resolved, but also for his decision, at the insistence of the East West Connect consortium, to direct the then state treasurer Michael O'Brien to sign a "side letter" guaranteeing the consortium compensation of more than $1 billion in the event that the court cases were successful or if for some other reason the contracts were cancelled (which Labor promised to do if it won the election), which was thought to be a contributing factor in the state having to pay what is thought to amount to $1.1 billion to EWC upon the declaration by the then new Andrews government to suspend work in December 2014, and the contracts eventually being terminated in June 2015. It was also revealed upon the contracts termination and release that the real cost amounted to $10.7 billion, $3.9 billion more than the $6.8 billion estimated cost by the Napthine government. In December 2015, the Victorian Auditor General revealed the cost of both sections of the East West Link would have been close to $22.8 billion in nominal terms.
