Upgrading Picton Road must be a "high priority" in next month's state budget, Keira MP Ryan Park said in parliament.
The call came days after the death of Ty Delaney, whom Mr Park described as "a talented artist and a passionate surfer, he was a mate to all".

"Picton Road is an important road and its improvement must be given high priority to ensure not only that we no longer hear of tragic accidents that each and every year take lives but also that the road can cope with population growth, particularly in the south-west traffic corridor, Mr Park said.
"We must ensure a safe and efficient mode of travel is available between those two key economic areas."
Mr Park said he would work to secure funding for an upgrade to duplicate Picton Road in the forthcoming state budget - due to be handed down on November 17 - and in future federal budgets.
"This road corridor is simply not up to the job and requires significant upgrading to improve its overall safety and efficiency," he said.
