Northbound Carriageway

The final component of the W2B

The Wells Crossing to Glenugie Section 2A project involves construction of 8km of new northbound only carriageway to median-separated dual-carriageway and is particularly significant as it represents the final component of the W2B section of the Pacific Highway.

Our scope includes clearing and grubbing, earthworks, drainage, plain concrete pavement, fauna crossings, road furniture, delineation and landscaping for two northbound lanes in a single carriageway.

In August 2019 Roads & Maritime Services (now Transport for NSW) directly awarded ACCIONA a contract for the Early Works for the final 8km Section 2A of the W2B roadworks from Wells Crossing to Glenugie, followed by award of the main contract in February 2020.

This was our fifth successful tender on the overall Pacific Highway W2B Upgrade. Factors contributing to our win included the timely delivery and safety achievements of our highly experienced teams on W2B Sections 10&11 and the Richmond River Bridge project.

Early Works commenced in August 2019 and overall completion was achieved in July 2021. Interestingly, our project team measured what is believed to be a new record of wet weather for our projects, recording more than 1018 mm of rainfall in a single month in mid-February 2020.

Following the success of our trial use of recycled glass in the paving of the W2B Sections 10 & 11 project, we worked collaboratively with RMS and Lismore Council to continue that initiative on this project.

Other components of the W2B project included the Sections 10 & 11 Civil Works, Section 10 Pavement and the Bridge over Richmond River at Broadwater. In addition, our sister company Australian Precast Solutions supplied all Precast Planks, Headstocks and Abutments for all 155 bridges in the entire Woolgoolga to Ballina Upgrade.

This project adds to our strong track record in having upgraded more than 289 km of the Pacific Highway’s 669 km between Hexham and Tweed Heads.
