You can walk around, under it, through it ... and soon you will be able to walk over it.

A $2.55 million skywalk and possible zipline will soon be built on the MCG.

Sports fans, locals and tourists will be able to climb up to 70 metres above the hallowed ground and walk across the western, city-end roof.

It will give visitors unrivalled views of Melbourne's world-class sporting precinct, the CBD and beyond.
