The South Australian opposition has promised to slash preparation and dismantling time for the Adelaide 500 V8 Supercars race to free up the Victoria Park precinct for an extra four weeks a year.
Opposition Leader Steven Marshall says if the Liberals win the state election on Saturday his government will put an extra $250,000 on the table to ensure the disruption to park users is minimised.
"The snail's pace at which the temporary grandstands go up and come down in Victoria Park is symptomatic of a Labor government that is old, tired and arrogant," Mr Marshall said on Sunday.
"The Adelaide 500 is a great event but there is no need for Victoria Park to be a construction site for six months a year."
At present the temporary grandstands take 25 weeks to be put up and brought down, with the Liberals promising to cut that to 21.
