Questions about M2 Financing

Here is an interesting comment off the internet, relating to the recently announced new financing for the M2 Widening project:
“Out of $740 million of new loans given by banks to Transurban, $465m are only for refinancing old M2 debt, leaving just $275 m for a project which costs $550 m to build. Where will the other $275 m come from? Transurban already sits on a mountain of debt which is continuously being rolled over (or should we say tolled over), but not paid back."
