Conmex operates a 110 km private toll road system in Mexico in the densely populated northeastern region of Mexico City.

This latest purchase comes weeks after the $53 billion fund manager bought a toll road in the US midwest for the massive sum of $7.5 billion, its largest ever infrastructure investment.

Other infrastructure assets owned by IFM Investors include ports in Sydney and Brisbane, Southern Cross Station in Melbourne, airports in Australia, the UK and Austria, and an LNG liquification plant in Texas.

Its owners include some of the biggest super funds in Australia, such as Sunsuper, AustralianSuper and HESTA. Smaller funds include Media Super, Kinetic and TWUSuper.
