THE $13 million Graham Farmer Freeway and East Parade intersection upgrade was completed and under budget in time for the start of 2017.
Transport Minister Bill Marmion announced the completion at the end of December and said construction to reduce congestion took 12 months and created 30 jobs.
“The project was delivered under budget by more than $1 million from the estimated $14 million budgeted,” he said.
Mr Marmion said as works progressed, there were early improvements with travel speeds increasing through the tunnel by 12 per cent in the morning peak periods.
He said the upgrade was undertaken as part of Main Roads WA’s traffic congestion management program.
An average of 80,000 vehicles travel through the busy intersection each weekday.
