Motorists attempting to navigate their way through Richmond are in a bit of a flap this morning after pranksters gave Swan Street a make-over, replacing every street sign with Hawks Street.

As Melbourne gears up for the battle of the birds in Saturday's AFL grand final, it appears a group of Hawthorn supporters decided to obliterate any reference to their red-and-white rivals from up north in Sydney.

Just after midnight, a motorist spotted four men wearing high visibility vests pulling up in a work truck and setting out traffic cones on Swan Street.

"Upon closer inspection I noticed them actually changing the street signs from Swan Street to Hawks Street," the caller to radio 3AW said.
