Traffic has been moved onto the new northbound lanes while work continues along the existing highway, which will form the southbound carriageway.
BMD Constructions won the $4.6 billion main civil works contract in 2017 for the for the Woolgoolga to Ballina section of the Pacific Highway.
The Pacific Complete consortium of RMS, Laing O’Rourke and Parsons Brinckerhoff won the design and delivery contract for this section.
NSW Minister for Regional Transport and Roads Paul Toole said the Woolgoolga to Ballina project was already delivering smoother, safer journeys for road users.
“The Pacific Highway duplication is one of the largest road infrastructure projects in Australia,” Mr. Toole said.
He says more than 80 per cent of the highway has been duplicated and the project is on the home stretch.
“We’re already seeing travel time reductions of around two hours, and fatal crashes have halved.”
Once completed, Mr. Toole says the Pacific Highway will have a four lane divided road from Hexham to the Queensland border, with improved travel reliability and better access for communities along the route.
The upgrade of this section is on track to open to traffic in 2020.
Following this, new sections of the highway will open progressively as they are completed.
