M1 Pacific Motorway Upgrade, Tuggerah to Doyalson consisted of a 12 kilometre section between Wyong Road, Tuggerah and Doyalson Link Road, Doyalson.
The upgrade caters for the increasing traffic volumes associated with growth in the Central Coast, Hunter and North Coast regions. Coffey Testing undertook geotechnical testing and material conformance testing for this project.
The project used over 200,000 tonnes of recycled crushed concrete which was produced on site to reduce waste and reduce import costs.
