  • Removal of the Karel Avenue median to facilitate future traffic management diversions;
  • Clearing of vegetation across the project footprint;
  • Establishment of the construction site office near Berrigan Drive; and
  • Traffic management diversions and change of flow in traffic extending along Karel Avenue.
