July 23 (Reuters) - Australian No. 1 toll road operator Transurban Group TCL.AX said on Monday it has bid for a 51 percent stake in the country's biggest transport infrastructure project, a A$16.8 billion ($12.4 billion) tollway through the middle of Sydney.
Transurban said a consortium it is part of made the offer for a controlling stake in the government entity building the so-called WestConnex despite the antitrust regulator's concerns that the deal may be bad for toll-paying motorists.
"Transurban remains confident that it will obtain all necessary approvals," the company said in a statement.
