Summary

The MR195 Cessnock Road Upgrade at Testers Hollow project involves the construction of a 670m roadway between Cliftleigh and Gillieston Heights.

  • Temporary drainage pipe under the preload surcharge embankment;
  • Tie-in to existing road at the northern and southern extents;

  • New drainage consisting of three pipes to allow water to pass under the new earth embankment and through the existing road embankment;
