As part of the NorthConnex project's commitment to reuse materials where possible, more than one million cubic metres of excavated rock and soil from tunnel excavation has been used to partially fill the Hornsby Quarry.

The Hornsby Quarry Road Construction Spoil Management Project has filled the void with spoil to a level that will allow Hornsby Shire Council to start rehabilitating the site to a public recreation area benefiting the local community. 

The project involved hauling spoil from the NorthConnex tunnelling sites to the Hornsby Quarry using the existing road network. Entry and exit to the quarry was via Bridge Road. Spoil was unloaded from trucks and transferred onto a conveyor system which safely carried the spoil to the bottom of the void.

The site will now be demobilised and rehabilitated in consultation with Council. Council has made a video about the project which is available here.

The project will now focus on removing equipment from the site and carrying out remediation works, including the resurfacing of Bridge Road. For more information read the media release.
