Parramatta Light Rail
Diona Ward Joint Venture - Early Works
Alliance Geotechnical is providing environmental, geotechnical & CMT testing services to assist in the relocation of underground utilities, upgrades to intersections, traffic light installation/modification, landscaping, and changes to street lanes and parking.
These enabling works are vital to keep the city moving and to minimise disruption for the people of Parramatta. These changes, while not directly along the Parramatta Light Rail route, will provide additional capacity and connections for everyone in the CBD before, during and after the light rail construction.
