The A$174m ($120m) Oaklands Crossing grade separation project in South Australia, which improves safety for road users and eases traffic congestion, has concluded.

The Oaklands Crossing project increases safety by lowering the rail line under the road, as well as removing the level crossing at the intersection of Morphett and Diagonal roads.

Each day, almost 42,000 vehicles use Morphett Road south of Oaklands Crossing. To the north of the crossing, an average of approximately 33,200 vehicles use Diagonal Road and nearly 8,700 use Morphett Road.

Jointly funded by the Australian Government, the state government and the City of Marion, the Oaklands Crossing project improves travel times by 23% at peak morning time and 25% at peak evening time.

Minister for Cities, Urban Infrastructure and Population Alan Tudge said that the removal of the level crossing made a huge difference to motorists in the area.

Tudge said: “The Oaklands Crossing project has been busting congestion and slashing travel time for eight weeks now.”

“And there is plenty more to come in Adelaide and South Australia with billions invested in infrastructure by the Morrison Government to get everyone home sooner and safer.”

Minister for Transport, Infrastructure and Local Government Stephan Knoll said the completion of this project was great news but there is lot more in the pipeline.

Knoll added: “The Marshall Government has built an $11.9bn pipeline of infrastructure works over the next four years so there’s still a lot of congestion-busting construction to come.”
