Rain has played havoc with parking for tonight's much anticipated clash between Carlton and Essendon at the MCG. 

A crowd of more than 75,000 is expected to turn out, to see the old rivalry reignited on football's biggest stage. 

But the Melbourne Cricket Club says that due to heavy rain, only half of Yarra Park will be available for parking.

All public entry gates will be open at their usual times, but the gates will close once the available spaces are filled.

If you're heading to the match don't get caught out – arrive early or take public transport.
